DATASHEET IEC Inlet Filters FN 9255 High performance dual-stage IEC C14 and C20 inlet filter Rated currents up to 20 A Approvals Excellent performance/size ratio IEC C14 or C20 inlet acc. IEC 60320-1 Medical versions (B type) acc. to IEC/EN 60601-1 Snap-in and rear mount versions (S and M type) Earth line choke version (Refer to FN9255 E) Performance indicators The FN9255 IEC inlet filter incorporates a dual stage filter into an IEC inlet that offers excellent filter attenuation in a compact housing. Using an IEC inlet, at the point of entry offers an optimized position and practical solution for integrating an EMC filter into any system. A wide selection of current ratings, output connections and mounting possibilities are available. The filter family also offers options that comply to medical application requirements and the entire family complies to all necessary safety approvals. {GPvar:L} Features and benefits Exceptional attenuation performance from 150kHz to 300MHz due to dual-stage design High saturation resistance and excellent thermal behavior Technical specifications Maximum continuous operating voltage Rated currents Operating frequency Approvals by rated current Rear and Front flange or snap-in mounting options 250 VAC, 50/60 Hz 2 to 20 A @ 40C max.
