Versatile Filtered Power Entry Module
Approvals■ Rated currents up to 6A
■ Single or dual-fuse holder
■ Fuses Ø6.3 x 32mm or Ø5 x 20mm
■ Voltage selector 100/120/230/240V
■ General purpose application
■ Optional medical versions (B type)
Typical applications
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.
■ Good conducted attenuation performance,
based on chokes with high saturation
resistance and excellent thermal behavior.
■ Rear/front or snap-in mounting.
■ Single or dual-fuse holder.
■ USA Ø6.3 x 32mm or EU Ø5 x 20mm fuses.
■ Two attenuation performance ranges.
■ Voltage selector 100/120/230/240V.
■ 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
■ Medical equipment
