Single-phase EMI filters

30 January 2019 Circuit & System Protection

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, while types FHSA/M and FIHA/M are chassis-mount filters. Exhibiting versatility, FFSA and FGSM units also feature input switches. The range includes many variations to cater for a wide variety of end-user needs.

The units feature a wide operating temperature range -40°C to 110°C, with full power operation to +50°C. Their shielded metal body prevents radiated emissions within the equipment and the medical version features a low, 5 μA at 250 V a.c. earth leakage figure for stringent medical applications. The range embraces current ratings from 1 A to 20 A versions, and dual-stage, chassis-mount versions are also available that provide greater attenuation levels than standard.

Saving on customer manufacturing costs, compact combined versions with single or dual fuse holder or fuse holder and switch reduce the amount of wiring and panel cutouts required. All models feature a bleed resistor and Faston terminals, and the IEC-inlet EMI filters come with a three-year warranty.
