Power Entry Module with EMC- Filter FN370
Versatile Filtered Power Entry Module
Rated currents up to 6 A
Approvals & Compliances
Single or dual-fuse holder
Fuses Ø6.3 x 32 mm or Ø5 x 20 mm
Voltage selector 100/120/230/240 V
General purpose application
Optional medical versions (B type)
Performance indicators
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.
