Versatile Filtered Power Entry Module
Approvalsn Rated currents up to 10A
n For one or two fuses
n Fuses Ø6.3 x 32mm or Ø5 x 20mm
n 2-pole rocker switch
n Voltage selector
n Optional earth line choke (E type)
Typical applications
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
desired solution.
n High conducted attenuation performance,
based on chokes with high saturation
resistance and excellent thermal behavior.
n Rear or front mounting.
n Single or dual-fuse holder.
n USA Ø6.3 x 32mm or EU Ø5 x 20mm fuses.
n 2-pole rocker switch.
n Voltage selector 110-120V / 220-240V.
n Custom-specific versions are available on
request.
n Portable electrical and electronic
equipment
n Consumer goods
n EDP and office equipment
n Single-phase power supplies, switch-mode
power supplies
n Test and measurement equipment
