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.
■ High conducted attenuation performance,
based on chokes with high saturation
resistance and excellent thermal behavior.
■ Rear or front mounting.
■ Single or dual-fuse holder.
■ USA Ø6.3 x 32mm or EU Ø5 x 20mm fuses.
■ 2-pole rocker switch.
■ Voltage selector 110-120V / 220-240V.
■ Custom-specific versions are available on
request.
■ Portable electrical and electronic
equipment
■ Consumer goods
■ EDP and office equipment
■ Single-phase power supplies, switch-mode
power supplies
■ Test and measurement equipment
