EMI filters for single phase AC supplies

December 06, 2018 // By Nick Flaherty
XP Power has introduced a range of chassis mount and IEC inlet EMI filters that satisfy the requirement for equipment to conform to the latest EMC emissions and immunity standards. The filters are suitable for any electrical or electronic equipment that is powered from a single phase AC supply.

Chiefly aimed at medical and IT equipment manufacturers, types FASA/M, FCSS, FDMM, FFSA, FGSM are IEC power entry inlets with integral line filters, and types FHSA/M and FIHA/M are chassis mount filters. Exhibiting versatility, FFSA and FGSM units also feature input switches. 

The filters have an operating temperature range -40 to 110 ºC, with full power operation to +50 ºC. This operating range permits operation in warmer ambient temperatures as the filters do not derate from +40 ºC. 

The filters’ shielded metal body prevents radiated emissions within the equipment and medical version features a low, 5µA at 250VAC earth leakage figure for stringent medical applications. The range embraces current ratings from 1A to 20A versions, and dual stage, chassis mount versions are also available that provide greater attenuation levels than standard.

Compact combined versions with single or dual fuse holder or fuse holder and switch reduce the amount of wiring and panel cutouts required and all models feature a bleed resistor and Faston terminals.

The series are available from Digi-Key, element14, Farnell, RS Components, approved regional distributors, or direct from XP Power and come with a 3-year warranty.
