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 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.
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.
