Product Highlights
The FIAM is a DC front-end module
providing transient protection, inrush current
limiting and Class B EMI filtering in a Mini-
size package. The FIAM enables designers
using Vicor 2nd Generation, 48Vin DC-DC
converters to meet the transient immunity
and EMI requirements of Bellcore, FCC,
ETSI and European Norms while protecting
system hardware from inrush current. The
FIAM accepts an input voltage of 36-76Vdc,
is available in 10 or 20A versions and
provides reverse polarity protection and
remote on/off.
FIAM is housed in an industry standard "half
brick" module measuring 2.28" x 2.2" x 0.5"
and depending upon model selected, may be
mounted on-board or in-board for height
critical applications.
