The traditional ALLFILM system of conventional medium and high voltage capacitors consists of aluminium foil and polypropylene, immersed completely in synthetic, flammable oil. Breakdowns in this kind of dielectric tend to result in permanent short circuits which take out the entire capacitor element, change the voltage conditions inside the capacitor and initiate a chain reaction of further failures of capacitor elements which will end up in the loss of the entire capacitor. In three-phase capacitors, this process is usually accompanied by the occurrence of phase asymmetries which may cause damage and catastrophic failure..
In our MSD™ medium voltage capacitors, we are using the metallised polypropylene so well known from LV power factor correction. Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress at the edges of the ALLFILM flat packs. Dielectric breakdowns insulate and regenerate by themselves, domino-like failures of series-connected capacitor elements are impossible. The capacitance remains practically unchanged throughout the operating life which is of particular interest for applications with tuning or detuning 3reactors. By that, phase asymmetries are impossible, and the costly star point monitoring by MV capacitor protection relais, typical for ALLFILM capacitors, becomes obsolete..
In fault situations, MSD™ capacitors do not create short circuits, hence they cannot be protected by blow-out fuses. The rising internal pressure can be reliably detected and signalled by the integrated pressure switch.
Unlike ALLFILM, MSD™ is manufactured without flammable liquid impregnants, and filled instead with eco-friendly solid, plant-oil-based resin. This offers advantages when using these capacitors in sensitive environment, in applications with high vibration stress, and during disposal at a later stage.
Available as three-phase ( WYE ) units in the range from 50 to 400kvar, for mains up to 12kV, 50/60Hz. Design in accordance with IEC60871, 61071 and 60110.
Surge protection capacitors are designed to protect high voltage motors and transformers from events with high transient overvoltages (e.g. lightning or switching surges). Keeping with our tradition of completely dry products, we have designed the first MV Surge Capacitor in self-healing technology: DSCTM.
In combination with the PD-free layout, the self-healing dielectric provides for extremely long operating life and highest operational safety. Unlike traditional oil-filled ALLFILM-capacitors which are bound to fail as soon as overvoltage or other stress factors have provoked a dielectric breakdown, the self-healing dielectric of DSCTM insulates the breakdown spot immediately and continues operation as usual.
Thanks to the solid polyurethane filling, the DSCTM can be installed in any mounting position: there are no liquids to threaten the environment or to be considered during disposal at the end of operational life.
With their uncomplicated terminals and the plastic housing, our surge capacitors do not only have a completely different optical appearance than ALLFILM capacitors, but also offer substantial savings in weight, space and cost.
The Utility model of this capacitor has been registered with German Patent and Trade Mark Office (DPMA) under file no. 20 2010 009 760.6.

With our long year know how and first-class production facilities, we are manufacturing capacitors in two basic technologies: MKP and MKPg™. In MKP capacitors, the winding elements are surrounded by poison-free vegetable oil, in MKPg™, capacitors, they are immersed by neutral insulation gas. When designing our product ranges, we focussed on the best possible technical features combined with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our power capacitors distinguish themselves by high AC-voltage load capacity and outstanding suitability for high rms and surge currents. Unlike some of our competitors who proudly quote fantasy ratings, we have really tested our capacitors to their rated values, allowing for sufficient reserves and guaranteeing flawless operation within the specifications.
Our capacitors are well-suited for all conventional applications in power factor correction, and can - if required - be adapted to your most critical and toughest requirements. They all have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM ").
Safe and reliable connection is guaranteed by our original CAPAGRIPTM capacitor terminal in the three sizes K, L and M. Having been copied by numerous competitors all over the world, our terminal has become a kind of standard for PFC capacitors. Be warned, however, of cheap copies which may be optically identical, but lacking the reliable grip of the original CAPAGRIPTM.
Technical layout, testing and application accord to IEC60831, UL810 and CSA 22.2. All capacitors with voltage ratings up to 660Vrms have been tested and approved by the CSA organisation to UL and CSA standards. Available in the range from 1.25 to 50kvar, for rated voltages of up to 1000Vrms/1400Vac. All MKPg Types listed in the catalogue can be supplied in identical shape as MKP version with oil-filling.
The E62-3ph capacitors stand out by their high AC-voltage load capacity. They have been designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion, a.m.o.
Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength.
The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation. The finger-proof CAPAGRIPTM screw terminals (rated IP20) make for simple and reliable connections and easy addition of IP20-resistors or reactors for discharge.
Our capacitors are well-suited for all conventional applications in power factor correction, and can - if required - be adapted to your most critical and toughest requirements. They all have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM ").
The standard design has a long-term stable capacitance tolerance of ± 5%. Tighter tolerances are available on request.
Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life.
The winding elements in our MKP(D) capacitors are surrounded by poison-free vegetable oil. Like our premium ranges of MKPg and MKP, the MKP(D) combines the best possible technical features with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our MKP(D) capacitors distinguish themselves by high AC-voltage load capacity and suitability for high rms and surge currents.
Our MKP(D) are available as single and three-phase capacitors and well-suited for all conventional applications in power factor correction. They have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM ").
Connection is made through convenient standard 6.3mm tab connectors. Technical layout, testing and application accord to IEC60831, UL810 and CSA 22.2.
Available in the range from 0.67 to 12.5kvar, for rated voltages of up to 525V rms.
The slim-line capacitors of our MKPc™-capacitors are well-suited for your standard applications in power factor correction and form a worthy add-on to our heavy duty ranges of MKPg™ and MKP. Following the excellent experience of our well proven MKPg™-capacitors, MKPc™ use basically the same parts and materials, special metallizing patterns and our SINECUT slitting technology. Likewise, the windings are immersed by neutral insulation gas.
The slim, tall design of the MKPc™ is optimized from a cost point of view. Nonetheless, the main technical features, eco-friendliness and operational safety are well within the requirements of all applicable power capacitor standards (namely, IEC60831, UL810 and CSA 22.2). All capacitors have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM ").
Safe and reliable connection is guaranteed by our original CAPAGRIP™ capacitor terminal in the sizes K and L.
Available in the range from 10 to 25kvar, for rated voltages of 400 to 440Vrms.
Using selected low-loss, self-healing polypropylene films and sophisticated manufacturing techniques such as high-vacuum drying and special coating patterns, the best of ELECTRONICON™s design expertise and highest care in manufacturing have been spent to prepare these capacitors for your most demanding applications, and toughest ambient conditions.
Our long-life MKP UHDTM contain three delta-switched capacitor elements of short height and large diameter. The optimized combination of winding length, film size, and winding geometry substantially reduces inherent power losses and allows us to achieve highest surge and rms current ratings as well as an overvoltage strength and switching stability which before would have been known only of impregnated paper capacitors. An MKP UHD™ handles up to 250% of its rated current and current surges of 400 x IN. The permitted operating temperatures range from -40°C up to 70°C maximum temperature (average over 24 hours: 60°C).
Other than the traditional impregnated Heavy Duty capacitors in ALLFILM or MKV (paper/film) technology, our capacitors have a dry dielectric allowing for very close tolerances of capacitance which is of particular importance in filter applications.
For the extremely unlikely event of malfunction, they are provided with BAMTM (overpressure break-action mechanism) for safe mode of failure.
Our original CAPAGRIPTM terminals L and M guarantee optimum sealing of the capacitors, and provide for convenient connection of cables up to 50mm². A special spring system guarantees reliable and durable operation of the clamp. They are rated IP20, i.e. protected against accidental finger contact with live parts. They also permit the direct connection of discharge reactors and resistor modules, as well as easy parallel connection of additional capacitors.
The slim, tall design of the MKPc™ is optimized from a cost point of view.

Our low-loss reactors are designed for such systems. They are available with adjusted (Dla) and fixed ratings (D)

The increasing call for shorter discharge periods can not be satisfied by traditional discharge means (fixed resistors). On the other hand, the installation of additional fast discharge resistors at the capacitor contactor would require increased expenses for material and installation.
Our discharge reactor replaces the common fixed resistors and additional rapid discharge resistors, and at the same time it substantially reduces the heat losses inside the capacitor bank..
Available for direct mounting on capacitor terminals (designs L and M) for up to 600Vrms or mounting on rails or even base for up to 690Vrms.
The power factor controller CR 2020 calculates the actual and reactive power in the mains from the measured current and voltage. It also determines if actual power is being consumed or delivered..
The controller identifies the power of the connected capacitor stages and connects or disconnects them in an optimized manner as required by the actual mains conditions. The regulation considers the frequency of changes in the reactive load and follows the principle of rotational switching. This guarantees that optimum power factor correction is achieved with the minimum number of switching operations.
It is also possible to determine a fixed capacitor value which is always added to the measured capacitor power. This is useful for the additional compensation of the reactive power of a transformer.
The integrated digital display can show the actual power factor, the mains frequency, the actual tariff, the programmed target power factor, the value of present harmonics, the connected and the missing capacitor power. This makes general and specific monitoring of the capacitor bank and its operating conditions possible. The power factor controller CR2020 is ready for operation with its preset functions immediately after installation without any modifications or adjustments.
Note: Available with 10 outputs.

In modern applications of power electronics, AC capacitors are among the most critical links in the chain of components when it comes to long operating life, safety and reliability of operation.
Decades of proprietary ELECTRONICON experience in metallizing capacitor films and designing high-end capacitors have created our very own Know-How, for instance in special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. This enables us to design AC capacitors with a high specific ratio of capacitance to volume, high AC-voltage load capacity and outstanding suitability for high rms and surge currents.
The cylindrical capacitors of our universal AC/DC series "E62" are perfect for non-sinusoidal voltages and pulsed currents, e.g. as damping or commutation capacitors switched in parallel to a thyristor, or connected in series with a resistor (damping of undesirable voltage spikes during the switching of power semiconductors). They can be widely used as supporting, smoothing, and surge discharge capacitors, further in AC filters, a.m.o. The low loss factor of our MKP dielectric compensates to a large extent for the losses caused by the non-sinusoidal voltages.
It goes without saying that all AC capacitors may as well be used for DC applications.
The E62s are housed in a hermetically sealed aluminium can which is filled with environmentally friendly plant oil as standard; optionally many of them can also be made available with a filling of inert gas. The gas filling is not only environmentally friendly, but also permits mounting in any position, while the oil-filled capacitors should - for electrical as well as environmental considerations - always be mounted vertically.
The excellent self-healing characteristics of our film metallization and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life.
The E62-3ph capacitors stand out by their high AC-voltage load capacity.

The standard design has a long-term stable capacitance tolerance of ± 5%. Tighter tolerances are available on request.
Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life.
The special kind of films and coating patterns used in our oil-filled E63-capacitors give them a high specific ratio of capacitance to volume and makes them extremely overvoltage proof. Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life. Hence the E63s are interesting particularly for applications with high AC ripple currents, e.g. as smoothing or supporting capacitors in buffer storage circuits, in sensitive environment with high safety requirements.
Note that the presence of an overpressure mechanism adds substantially to the self-inductance of the capacitor, and limits the surge current rating. If self-inductance and surge current are important issues, then our E50 or E53 ranges may be considered as a more adequate option.

Harmonic distortion is a key issue not only in low voltage, but also medium and high voltage Power Factor Correction. The installation of detuning reactors helps to protect capacitor installations from dangerous and devastating resonances by preventing any amplification of harmonic currents and voltages caused by resonance between capacitors and inductances in the mains. At the same time, it reduces the overall level of harmonic distortion in the mains.
Note that the presence of an overpressure mechanism adds substantially to the self-inductance of the capacitor, and limits the surge current rating. If self-inductance and surge current are important issues, then our E50 or E53 ranges may be considered as a more adequate option.
The PK16™ capacitor can be universally used for the assembly of low inductance DC buffer circuits and DC filters; with its high energy density it can replace banks of series-connected electrolytic capacitors as well as large film capacitors in rectangular cases. The capacitance in a DC buffer circuit must be sufficiently sized to both handle and smoothen the occurring ripple currents.
The traditional use of series-/parallel-connected electrolytic capacitors offered large capacitance at seemingly low cost, however the low cost per microfarad is countered by the very low current strengh, the high sensitivity to voltage and current surges, as well as a substantial risk of failures in the field, resulting in high maintenance cost.
Our advanced know-how in special capacitor film coating and many years of practical experience in designing and manufacturing capacitors have allowed us to develop our PK16™ range with high capacitance density. With fivefold the current strength of conventional electrolytic capacitors, it is not necessary to provide the same capacitance in film technology to handle a given current.
Instead, the user now gets a superior technical solution within the same - or even less - space, offering: Thanks to its compact cylindrical design this capacitor is ideal for both the electrical and mechanical requirements of high-speed IGBT converters.Its robust terminals and the robust fixing stud allow for very simple, reliable mounting and connection that unites lowest inductance and supreme current strength. The particularly large clearance and creepage distances make this design suitable for a wide range of operating voltages. As a result, existing standard converter concepts can easily be adapted to new applications without having to change the principal construction and to re-approve the entire system.

Thanks to the special kind of films and coating patterns used in our E56/E59-capacitors, clever winding geometries and refined internal construction, they unite large capacitance, very small self-inductance and high surge current sustaining capability (up to 700kA) as well as the possibility of high rms currents (up to 750A). Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress and instabilities at the edges of flat packs. Special terminals allow for additional reduction of the self-inductance.

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance and creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor. Decades of proprietary ELECTRONICON experience in metallizing capacitor films and designing high-end capacitors have created our very own Know-How, for instance in special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. This enables us to design AC capacitors with a high specific ratio of capacitance to volume, high AC-voltage load capacity and outstanding suitability for high rms and surge currents.
Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread. Along with their very good ratio of capacitance to volume, these capacitors do also have high pulse strength and very good self-healing characteristics without loss of capacitance. For the sake of optimised self-inductance, the E51s are made without safety mechanism; by clever internal design they can be laid out and rated in such manner that partial dielectric discharges and consequential risk of failures in the customer?s application are reduced to a minimum.
Who said it has to look like a surge capacitor? They look different, and as a matter of fact, they are. Surge protection capacitors are designed to protect high voltage motors and transformers from events with high transient overvoltages (e.g. lightning or switching surges).

Any device is only as reliable as the sum of its components. With more than fifteen years of experience in manufacturing tuned and detuned filter reactors for power factor correction, we are now offering our range of line reactors for application in power electronics. Same as with our capacitors, we focus on minimized power losses and maximum durability of the reactor – optimized for your application.
Made of high-class transformer sheets and copper wire or aluminium band. Vacuum-impregnated with environmentally friendly, low-styrole resin for long operating life, high voltage strength and low noise levels. Standard terminals: copper terminal lugs, optional with screw-terminal blocks or cables. Integrated reversible thermal switch for monitoring of the reactor and control of external disconnection in case of overheating. Our standard range covers 400V 50Hz up to 300A per phase. Other values are available on request.
Our capacitors of the E12 and E33 series are universally-suited for lighting and motor applications as well as power factor correction and power electronics. Their winding element of self-healing polypropylene film is immersed in eco-friendly vegetable oil and designed for highest requirements regarding operational life and functional safety even at high operating temperatures and other extreme conditions such as high humidity.
Connection is made through a convenient push wire terminal which includes the discharge resistor. The hermetical aluminium can is provided with an integrated overpressure safety mechanism (break-action mechanism, " BAM ") that disconnects the capacitor irreversibly from the supply in the event of a failure.

Our E05 capacitors, classified acc. to EN61048 as type A components, are housed in cans of flame retardant plastic, without any special liquid or gas filling. They can optionally be connected either through a convenient push wire terminal or flying leads. A discharge resistor is included as standard.
The E12/E33 ranges comply with the "Type B" classification under lighting standard IEC/EN61048 as well as with "Class P2" under motor capacitor standard IEC/EN 60252-1.Please mind our safety remarks on the use of lighting capacitors in critical environment.
A magnetic ballast can be over-corrected by a series-connected capacitor, in such a way that the capacitive reactive power of the capacitor can cover the inductive reactive power created by two magnetic ballasts. It should be noted that the series resonance between capacitor and ballast causes a voltage rise above rated mains voltage within the capacitive part of the circuit. The advantage of this dual connection lies in the elimination of flickering effects of the emitted light.
In networks with audio-frequency signals above 250 Hz this kind of connection is often required by the energy supplier. Our lighting capacitors for series connection are rated for continuous operation at 480V rms and specially designed for operation at ambient temperatures of up to 100°C. The capacitor windings within the hermetically sealed can are immersed in a special insulating oil that also protects them from humidity.Available up to 9.6µF 480V rms. Approved by VDE as "Type B" acc. to IEC/EN61048 and IEC/EN61049..

They can optionally be connected either through a convenient push wire terminal or flying leads. A discharge resistor is included as standard.
In addition to the standard specifications for type A capacitors, the E05 are provided with an integrated patented temperature fuse, responding to the heat typically generated during the fault of a capacitor. It is possible to leave out the fuse for very cost-sensitive applications (range E01), however the saving is not substantial compared with the version which includes the safety device.
Since both the E05 and the E01 series are "open" systems, i.e. not hermetically sealed, they are recommended for use in uncritical environment only. Please mind our safety remarks on the use of lighting capacitors in critical environment. Available for 250Vrms, capacitance range up to 55µF. Full range approved by VDE to EN61048 and EN61049, further by GOST.
Our E06 capacitors, classified acc. to EN61048 as type A components, are housed in aluminium cans, without any special liquid or gas filling. Connection is made through a convenient push wire terminal which includes the discharge resistor.
In addition to the standard specifications for type A capacitors, the E06 are provided with an integrated patented temperature fuse, responding to the heat typically generated during the fault of a capacitor. It is possible to omit the fuse for very cost-sensitive applications (range E02), however the saving is not substantial compared with the version which includes the safety device.Since both the E06 and the E02 series are "open" systems, i.e. not hermetically sealed, they are recommended for use in uncritical environment only.
Please mind our safety remarks on the use of lighting capacitors in critical environment. Available for 250Vrms, capacitance range up to 60µF. Full range approved by GOST.
Our capacitors of the E12 and E33 series are universally-suited for lighting and motor applications as well as power factor correction and power electronics. Their winding element of self-healing polypropylene film is immersed in eco-friendly vegetable oil and designed for highest requirements regarding operational life and functional safety even at high operating temperatures and other extreme conditions such as high humidity.
Connection is made through a convenient push wire terminal which includes the discharge resistor. The hermetical aluminium can is provided with an integrated overpressure safety mechanism (break-action mechanism, " BAM ") that disconnects the capacitor irreversibly from the supply in the event of a failure.
