ZEZ - High Voltage DC Capacitors

Case Style:                 Capacitance:                   Voltage:

Square                         2uf to 6800uf                  1600V to 16000V (16kV)         

 

The capacitors are self healing, dry MKP technology. Elements are enclosed in a cylindrical aluminium case filled with oil based, non toxic, biodegradable, environmentally friendly, solid matter. The case is fitted with an overpressure disconnector and an M12 mounting stud, which is also used for the protective conductor connection.

ZEZ - DC Link Power Capacitors (Square)

Case Style:                 Capacitance:                   Voltage:

Square                         50uf to 4500uf                600V to 6000Vdc        

 

The capacitors are self healing, dry MKP technology. The capacitors are designed for direct mounting to industry standard IGBT modules saving cost of expensive DC bus bars and reducing labour time.

ZEZ - DC Link Power Capacitors (Cylindrical)

Case Style:                 Capacitance:                   Voltage:

Cylindrical                   1uf to 800uf                     600V to 8000V

 

DC Power capacitors with a voltage range upto 8000V (8kv) reducing the need for series / parallel combinations of DC screw terminal electrolytic capacitors.

ZEZ - IGBT Snubbers (Grey Boxed)

Case Style:                 Capacitance:                   Voltage:

Square                         0.25uf to 1uf                    2000V to 4500V          

 

IGBT snubber capacitors designed for direct mounting to most industry standard IGBT modules.

ZEZ - IGBT Snubbers (Cylindrical)

Case Style:                 Capacitance:                   Voltage:

Square                         0.5uf to 25uf                    1200V to 6800V          

 

The self-healing dry capacitor elements are enclosed in a cylindrical plastic case sealed with PU resin. They are made of metallized PP film, MKP system. This enables the unit to carry high inrush currents with low self-inductance and series resistance.

ZEZ - IGBT Snubbers (Black Boxed)

Case Style:                 Capacitance:                   Voltage:

Square                         0.25uf to 1uf                    2000V to 4500V          

 

IGBT snubber capacitors designed for direct mounting to most industry standard IGBT modules.

ZEZ - GTO Snubbers

Case Style:                               Capacitance:                             Voltage:

Cylindrical                                 0.1uf to 25uf                              1000V to 8000V

 

The self-healing capacitor elements are enclosed in a cylindrical plastic case sealed with PU resin. They are constructed from PP film technology MKP. This enables the unit to carry high inrush currents with low self-inductance and series resistance.
