Fully Potted Three-Phase Du/dt Filter (Protection Class: IP00 – IP66)
Description
Reduce voltage rise to < 500V / µs – protect electrical loads and insulation cost-effectively.
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 acceptable values and prevents overvoltages on long supply lines. Losses and heating are minimised and the leakage current is reduced. By limiting the voltage gradient, the motor insulation is protected and the service life is extended.
The EMC interference in the radiation range from 1 MHz to 30 MHz is also reduced.
Voltage rises are reduced to < 500V / µs.
