    A power line filter, also known as EMI/RFI power line filter, is an electronic passive device which is installed between the power line and the equipment in order to suppress electromagnetic interference (EMI) or radio frequency interference (RFI). Due to high attenuation performance, 1-phase and 3-phase EMI AC power line filters on ATO.com are good solutions for EMI suppression, which provide a reliable protection for a wide range of applications in the industrial areas. The current rating ranges from 1A, 10A, 20A, 40A to 100A. To achieve a higher performance in interference attenuation, 3-phase dual-stage EMI power line filters are also available here.
    ATO EMC line filters for variable frequecny devices for sale now. The filters work on the input / output side of VFD, with current rating from 6A to 1000A and rated voltage 250V/440V AC 50Hz/60Hz. With low leakage current and high interference suppression capability, it is a best solution for protecting variable frequency drives, servo motors, and frequency converters and extend their service life.
