Line filters and sine wave filters help reduce noise pollution, so that machines and installations can be operated in a safe and stable manner, and in accordance with the required standards. For example, filters are often used as inputs filter for frequency converters or as a sine wave between frequency converters and motors. We supply filters in the standard range of 7A to 180A, as well as for nominal voltages between 400 VAC and 480 VAC.



For use in automation technology, e.g. as input filter for frequency inverter:

To increase reliability and quality
To reduce interference on high-voltage lines
To reduce disturbing noise
To reduce high frequency interference voltages
To reduce EMC problems
