LCR's 3 Phase EMI filters (RFI filters, EMC filters) are typically used in Power Electronic products. These EMI filters attenuate mains-borne EMI generated back into the power line. LCR's 3 phase EMI filters also protect sensitive electronics and make them less susceptible to surges, Electrostatic Discharge (ESD) and other harmful voltage and current surges. Typical applications for these EMI filters (RFI filters, EMC filters) are in three-phase industrial drives, controllers, frequency converters and industrial machine tools.
