The FN 390 power entry module combines
an IEC inlet, mains filter with single or
dual-fuse holder, voltage selector and 2-pole
rocker switch. Choosing FN 390 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.
Multiple options designed to offer you the
