dv/dt filter compact plus Voltage Peak Limiter

The dV/dt filter compact plus Voltage Peak Limiter has two components: The dV/dt reactor

and the voltage limiting network (Voltage Peak Limiter). The voltage limiting network cuts-off

the voltage peaks and feeds the energy back into the DC link.

The dV/dt filter compact plus Voltage Peak Limiter is designed for use with motors for which

the voltage strength of the insulation system is unknown or insufficient.

The dV/dt filters compact plus Voltage Peak Limiter limit the voltage load on the motor

cables to values which correspond to limit value curve A according to IEC/TS 60034-

The rate of voltage rise is limited to < 1,600 V/µs, the peak voltages are limited to < 1400 V.
