FN 9255 High performance dual-stage IEC C14 and C20 inlet filter Rated currents up to 20 A 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) 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. Features and benefits Exceptional attenuation performance from 150kHz to 300MHz due to dual-stage design High saturation resistance and excellent thermal behavior Rear and Front flange or snap-in mounting options Optional medical versions (B type) comply with the requirements of IEC/EN 60601-1 for creepage and clearance, leakage current and high potential testing Optional earth line choke see FN 9255 E versions Typical applications Medical devices (MDD) In-vitro diagnostic medical devices (IVDD) Computing & accessories LCD and OLED Displays Test and measurement equipment Household and similar products as per IEC/EN55014 Portable electrical and electronic equipment Small to medium-sized machines Single-phase power supplies, switch-mode power supplies (SMPS) Technical specifications Maximum continuous operating voltage 250 VAC, 50/60 Hz Rated currents 2 to 20 A @ 40°C max.
