EMC Filters

Interesting Facts About EMC Filters

EMC-filters are used for suppressing line-conducted interferences. The spreading is prevented by a maximum level of impedance mismatch. The filtering effect extends in both directions. This means that both the interference from the consumer to the network and the interference from the network to the consumer are suppressed.

REO du/dt filters suppress the voltage increase to tolerable levels due to their design. For short lengths of cable between the frequency inverter and the motor, a du/dt filter limits the increase speed and is the ideal link between frequency inverter and motor.
