Flexible single-stage and double-stage IEC inlet filter series
The filters come as an ultra-compact switch and fuse holder unit with a versatile flange mount system for fast and flexible installation. Despite the compact design of the filter with a height of only 46mm, the combined unit with dual fuse holder provides extra space for a spare fuse. The dual pole power switch disconnects all poles of the device from the mains and can be removed for maintenance thanks to the integration into the combined unit in order to specifically avoid accidental connection and power-on. For cabling inside the device, the IEC inlet filters are available with proven fast-on tabs or spring cage terminals for faster and vibration-proof wiring. The new flange mount system with either horizontal or vertical mounting holes provides maximum flexibility for front or back mounting. Optimal shielding is achieved even against strong magnetic fields thanks to the RF tight joining of the flange frames with the deep-drawn steel housings.
The FN9280 series is equipped with proven single-stage EMC/EMI filters. The FN9290 series requiring the identical panel cutout has a double-stage EMC/EMI filter with an attenuation of up to 80dB and is well suited for applications with higher interference levels. The B versions of both series with a minimal leakage current of 5uA max. are suited for use in medical devices. The FN9280 series can optionally be delivered as E version with earth line choke for additional asymmetric interference suppression.
The filters are designed for currents from 1 to 10A with a rated voltage up to 250Vac. They are approved for worldwide use according to UL, CSA, ENEC and CQC and conform to RoHS and REACH. The B-versions comply with the requirements of the active third edition of the safety standard IEC/EN60601-1 for medical devices.
