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.
Versatile filtered power entry module
