Product Highlights
The 28V
DC
MIL-COTS VIPAC family of
power systems is a new class of user-
defined, modular power solutions for the
most demanding military applications. It
incorporates preassembled and tested front
ends (M-FIAM5B or M-FIAM9), Vicor Maxi,
Mini and Micro series DC-DC converters
(H or M-Grade), a choice of output
connections and mechanical platforms. The
28V
DC
VIPAC can be specified with 1, 2 or 3
outputs with voltages as low as 3.3V
DC
to as
high as 48V
DC
and power levels from 40 to
400W per output. Additionally, the wide trim
range of the modules can provide operating
voltages from 500mv to 52.8V. The MIL
VIPAC is available with an input of 28V
DC
in a
variety of packages with profiles as low
as 0.75”.
For additional technical or design information;
or to create a 28V
DC
VIPAC tailored to your
specific requirements using Vicor’s online
configurator, please visit vicorpower.com.
