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.
