VIPAC Array
Family
of DC-DC Converters
Up to 750 Watts
Description & Installation Guide
Product Description
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, DC-DC converters.
Using Vicor’s PowerBench design tools, designers are able to quickly specify VIPAC
Arrays with standard 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 any budget or design. Short cycle time and rapid delivery make VIPAC Array a
valuable tool for power system prototyping and development efforts as well.

Product Overview Application Tips
32
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
module configurations enabling Arrays of identical output voltage and current ratings 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, scalable 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.

Remote Sense
A remote sense feature is provided on outputs configured with Mini or
Maxi sized DC-DC converters. The output sense connections must be
terminated either locally or remotely and should not be left open. VIPAC
Arrays provided with the optional LugMate connectors are configured
for local sensing via removable jumpers installed at the factory. The
jumpers will need to be removed if access to the secondary control
function is made via mating connector 16385 and connections will
need to be established for local or remote sensing.
Wire Routing
Avoid routing wires over the VIPAC Array Power System.
Do not bundle Input and Output leads together.
Parallel Outputs
The VIPAC Array can be configured with parallel modules for increased
power or redundancy. When output terminations other than the
LugMate are specified the user must properly connect the output and
sense terminals. At no time operate a paralleled output with a load
applied to only one module! (See Output Connections)

sensing the +Sense pins should be tied to the same point on the +Out power
bus; the -Sense pins should be tied to the same point the -Out power bus.
** There should be one master module, this is realized by choosing one
module to be the master and shorting the SC to –S on the other module.
Units configured from the factory as paralled will already have this
configured.

Please Note:
VIPACs that contain multiple modules configured as a single output
(paralleled for power or redundancy) MUST have their Outputs and
Sense connected to each other at the load.
DO NOT OPERATE A PARALLEL CONFIGURATION WITH ONLY ONE MODULE CONNECTED.
Additi onally o ne module must be designated as “Master” by having all other modules configured
as “Boosters”. Boosters are c reated by shorting the S C pin t o –S.

Trimming
Provisions have been made on PlugMate output connectors for adding
resistors to trim the output voltage up or down. Consult the design
calculator, for Rd/Ru trim resistor values, located at vicorpower.com.
