Overvoltage shut down[a]
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 systems.
The VI-IAM, in combination with Vicor
24, 48 and 300 Vdc input modules,
provides a highly efficient, high density
power system with outputs from 1 to 95 Vdc
and power expandable from 25 to 800 W.
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.
