Filter Type MSF

Line filters and sine wave filters help reduce noise pollution, allowing installations and machines to be operated in a safe and stable manner, in accordance with the relevant standards. For instance, filters are often used as input filters for frequency converters, or as sine wave filters between a frequency converter and motor. We supply filters in the standard range of 7A to 180A, as well as for nominal voltages between 400 VAC and 480 VAC.



Motor sine wave filters MSF are placed between the output of a frequency converter and a motor:

To extend the life span of the engine
To reduce voltage spikes, which can damage the insulation
To reduce noise pollution
To reduce high-frequency reactive current components
To reduce EMC problems
With the use of the MSF, the use of shielded motor cables in a large number of applications can be dispensed with
