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 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.
This combination provides compliance
with the transient requirements of
Bellcore, British Telecom and IEC
standards, and meets the EMI/RFI
specifications of Bellcore, British Telecom
and FCC Part 15, Subpart B and EN55022.
