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.
