ComPAC™
DC-DC Switchers
Features & Benefits
RoHS Compliant (VE versions)
Inputs 24, 48 and 300VDC
Any output: 1 – 95VDC
Meets EN55022 Class A
conducted emissions (See Notes)
cULus, cTÜVus (60950-1)
CE marked (LVD)
80 – 90% efficiency
Up to 10W/in3
Overall disable
Overvoltage shut down
Product Description
ComPAC delivers up to 600W from
one, two, or three outputs in a package
just 0.99in [25,2mm] in height with the
field‑proven performance, high efficiency
and high reliability inherent in Vicor
component‑level power converters.
ComPAC meets conducted emissions of
EN55022 Class A. ComPAC is offered with
input voltage ranges optimized for industrial
and telecommunication applications and
provides extended input over voltage
capability, undervoltage lockout and
overall disable.
Packaging Options
Conduction Cooled Models Available.
Add “CC” to the end of the part number.
(Consult factory for details.)
Extended heat sink available.
Add “–H1” to end of part number.
