Power capacitors for PFC
PFC-Power capacitors for power factor correction allow the configuration of fixed capacitors, automatic PFC systems and harmonic filters for all requirements.
Our capacitors are designed with dry technology due to safety reasons. All capacitors are designed according to the international valid standards EN60831-1 and -2 and are monitored in accordance with our quality management system.
Our quadruple safety system guarantees the safe operation and a long lifespan.
Two construction forms are available:
cylindrical aluminum housing
(mainly for use in the cabinet for the development of automatically controlled systems)
Square capacitor in steel housing
(mainly for fixed PFC or exposed installation)
The main requirements of power capacitors are a long lifespan and a high level of safety. A quadruple safety system for optimum protection:
- Selfhealing dielectric
- Dry impregnation (PCB free)
- Over pressure tear-off fuse
- Integrated discharge resistors
The over pressure tear-off fuse: the main protection element
If voltage-related, thermal overloads or numerous breakdowns at the end of the lifespan of the capacitor lead to increased self-healing processes with the corresponding development of gas, excess pressure builds up in the capacitor. The capacitors are generally equipped with an over pressure tear-off fuse to avoid the capacitor can bursting.
This protection feature consists of nominal break points in the internal connection wires. If there is excess pressure in the capacitor, the capacitor can expands and the electricity supply to the active capacitor elements is irreversibly interrupted at the nominal break point.
This safety principle is only reliably effective within the defined (specified) load and overload limits.
