Schaffner FN9280/FN9290 IEC inlet filter range

The Schaffner FN9280 and FN9290 IEC inlet filters are equipped with C14 type IEC appliance inlets. Tight RF jointing comprising flange frames with deep-drawn steel housings provide a high degree of shielding against strong magnetic fields.

The flange mount system offers either horizontal or vertical mounting holes to enable front or back mounting.

The 9280 filters have a single-stage topology and the FN9290 is a two-stage device offering an insertion loss of 80 dB typically. Both have a compact design with a height of 46 mm and a dual fuse holder for a spare fuse.

The dual pole power switch isolates the filters from the mains and can be removed for maintenance. The B versions of both series have a minimal leakage current of 5 µA maximum and are suitable for medical devices.

The E versions are provided with earth line choke for additional asymmetric interference suppression.
