PRODUCT INFORMATION
The 28 Vdc 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 Family DC-DC converters (H or M-Grade),
and a choice of output connections and mechanical
platforms. The 28 Vdc VIPAC can be specified with
one, two or three outputs with voltages as low as 3.3
Vdc to as high as 48 Vdc and power levels from 50 to
400 W per output. Additionally, the wide trim range of
the modules can provide operating voltages from 500
mV to 52.8 V. The MIL-VIPAC is available with an input
of 28 Vdc in a variety of packages with profiles as low
as 0.75".
Consult Powerbox Sales for additional technical or
design information to configure a tailored system.
