Mitsubishi FR-S5NFSA-0.75K EMC Filter

The Mitsubishi FR-S5NFSA-0.75K is a Class-A EMC filter designed to suppress electromagnetic interference generated by variable frequency drives on the mains supply. It reduces high-frequency disturbances across the 150 kHz to 30 MHz band, ensuring compliance with EMC regulations and preventing conducted emissions that could affect other equipment. This single-phase filter is rated for 0.75 kW at 200–240 V AC (±10%, −15%) and integrates directly into the input mains of compatible Mitsubishi FR-S500, FR-E700, and FR-D700 series inverters.
