Description


Reduce voltage rice to < 500V/µs - electrical consumrs and insulation will protected with low costs. 

A simple and inexpensive method for reducing the rate of voltage rise is to use a du / dt filter. The filter attenuates the voltage rise to acceptable values and prevents overvoltages on long supply lines. Losses and heating are minimized and reduces the leakage current. By limiting the rate of voltage rise, the motor insulation is protected and thus increases the service life.

Also, the electromagnetic interference can be reduced in the radiation range of 1 MHz to 30 MHz.

Voltage risers is reduced to < 500V/µs.
