Product Highlights
The Input Attenuator Module (VI-IAM) is
a component-level, DC input front end
filter designed to occupy minimum board
space while providing maximum protection
for today’s sophisticated electrical

s
systems. The VI-IAM, in combination
with Vicor 24, 48 and 300Vdc input
modules, provides a highly efficient, high
density power system with outputs from
1 to 95Vdc and power expandable from
25 to 800W. Your system will benefit from
the small size, efficiency and inherent
reliability of Vicor’s component-level
converters, while meeting the toughest
demands of Telecommunications and
Industrial power applications.
