Product Highlights

The AIM (Alternating Input Module)
is an AC front-end module which
interfaces directly with worldwide
AC mains. The AIM provides line
rectification, EMI/RFI filtering,
transient protection and inrush
limiting in a half brick package
measuring 2.28" x 2.4" x 0.5".

The AIM is used in conjunction with
Vicor VI-200 or VI-J00 DC-DC
converters to realize a universal AC
input, high density, low profile
switching power supply with outputs
from 1-95Vdc and a total power rating
up to 200W. An external capacitor is
used to satisfy system hold up
requirements. Internal EMI filtering
meets EN55022 and FCC part 15,
class A emissions limits.
