Line filter

A line filter reduces interference emission via the supply system cable, which is generated by the inverter. The line filter mainly serves to meet interference voltage limit requirements in the frequency range from 150 kHz to 30 MHz at the line connection. In addition, a line filter dampens the interference from the grid affecting the inverter. The selection of the line filter depends on the nominal line current and the line voltage of the frequency inverter.

Select the line filter type based on the following table.
