Fully Potted Three-Phase Du/dt Filter (Protection Class: IP00 – IP66)
Description
Reduce voltage rise to < 500V / µs – cost-effectively protect electrical loads and insulation.
A simple and cost-effective method to reduce the voltage rise rate is to use a du/dt filter. The filter dampens the voltage rise to tolerable values and prevents overvoltages on long supply lines. Losses and heating are minimized, and the leakage current is reduced. By limiting the voltage steepness, the motor insulation is protected, thus extending its lifespan.
EMC disturbances in the radiation range from 1 MHz to 30 MHz are also reduced.
Voltage rises are reduced to < 500V / µs.
