The VIPAC Array is a highly flexible system of DC input, power
building-blocks that can be configured with as many as four
user definable outputs on a low profile, coldplate chassis.
VIPAC Array offers the convenience of a prepackaged, chassis
mount solution with the performance and power density of
Vicor’s Maxi, Mini, Micro Series modules, DC-DC converters.
Using Vicor’s VCAD configuration tool, (vicorpower.com/vcad),
designers are able to quickly specify VIPAC Arrays with stan-
dard inputs of 24, 28, 48, 72, 110, 150, 300 or 375 Vdc and
standard outputs from 2 to 48 Vdc at power levels up to 600
Watts per output. A total of 8 standard chassis configurations
offers the user a choice of power and mechanical options to fit
most designs. Short cycle time and rapid delivery make VIPAC
Array a valuable tool for power system prototyping and devel-
opment efforts as well.
For technical information refer to “Design Guide & Applications
Manual for Maxi, Mini, Micro Family DC-DC Converters and
Accessory Modules”
Vicor’s VCAD configuration tool provides expedited part config-
uration, part number, price and delivery information by selecting
standard Maxi, Mini, and Micro modules for use within the VIPAC
Array based on the application requirements. The modules are
chosen based on the input and output requirements and the
closest, but higher power level that is available to that specified.
Specifications for these can be found on their respective
data sheets.

VIPAC Arrays are ideal for use in distributed and modular
power systems where power density and reliable operation are
critical. A current share option is available on single output mod-
els enabling them to be used in applications requiring either
redundant operation or kilowatts of power. The 300 and 375
Vdc input versions can be coupled to a bulk AC Front-end to
create a modular, scaleable power supply serving a variety of
power architectures from centralized to distributed. VIPAC Arrays
include internal fusing, a global enable / disable function and
connectorized input and output terminations to speed system
installation while a versatile coldplate chassis simplifies thermal
management and mounting.
