THREE-PHASE-DV/DT FILTER

CNW 806

Reduce voltage rice to < 500V/µs – electrical consumers 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 or throttle. It dampens the voltage rise to acceptable values and prevents overvoltage’s on long supply lines.

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