Product Highlights
ComPAC delivers up to 600W from
one, two, or three outputs in a package
just 0.99” (25,2mm) in height with the
field proven performance, high
efficiency and high reliability inherent
in Vicor’s component level power
converters. ComPAC meets British
Telecom and European norms for input
surge withstand and meets conducted
emissions of EN55022 Class B.
ComPAC is offered with input voltage
ranges optimized for industrial and
telecommunication applications and
provides extended input overvoltage
capability, input reverse polarity
protection, undervoltage lockout, and
master disable.
