ARCOL / Ohmite AF IEC Inlet Single-Phase EMI Filters

ARCOL / Ohmite AF IEC Inlet Single-Phase Electromagnetic Interference (EMI) Filters designed to suppress undesirable electrical disturbances in power lines. ARCOL / Ohmite AF EMI filters come in three designs and are available with a fuse and switch. The series limits the amplitude of interfering voltages on AC power lines and prevents them from propagating into or out of the filtered equipment.
