    A power line filter, also known as EMI 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, EMI power line filters on ATO.com are good solutions for EMI suppression, which provide EMI protection to a wide range of applications in the industrial areas for single-phase and 3-phase power. To achieve a higher performance in interference attenuation, 3-phase dual-stage EMI power line filters are also available here. Select a line filter in high performance and protect your equipment or device from EMI/RFI to improve its stability.
