DATASHEET IEC Inlet Filters FN 370
Versatile Filtered Power Entry Module
Rated currents up to 6 A Approvals
Single or dual-fuse holder
Fuses Ø 6.3 x 32 mm or Ø 5 x 20 mm
Voltage selector 100/120/230/240 V
General purpose application
Optional medical versions (B type)
The FN 370 power entry module combines an IEC
inlet, a mains filter with a single or dual- fuse holder
and a voltage selector. Choosing FN 370 product line
brings you the rapid availability of a standard filter
associated with the necessary safety acceptances.
Standard IEC connector filters are a practical solution
helping you to pass EMI system approval in a short
time. A wide selection on amperage ratings, fuse
options, mounting possibilities and filters for medical
applications are designed to offer you the desired
solution.
