Product Overview
The VIPAC Array is a highly flexible system of DC input, and power building
blocks that can be configured with as many as four user-definable outputs on a
low-profile, cold plate 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, and DC-DC converters.
For technical information refer to the Design Guide & Applications Manual for Maxi, Mini, Micro Family DC-DC Converters and Accessory Modules.
Features:
- Optional current share (single output)
- Onboard fusing
- Global enable/disable
Vicor’s VCAD configuration tool provides expedited part configuration, 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.

Product Usage Instructions
Input and Output Connections
The VIPAC Array requires DC input and provides multiple user-definable
outputs. To connect the inputs and outputs:
- Ensure that the input voltage is within the specified range for the VIPAC Array variant being used.
- Connect the positive and negative terminals of the DC input source to the designated input terminals on the VIPAC Array.
- For each desired output, connect the positive and negative terminals of the load to the corresponding output terminals on the VIPAC Array.
Mounting Options
The VIPAC Array offers various mounting options:
- Chassis Mount: The VIPAC Array can be mounted on a chassis using appropriate screws and mounting holes.
- Coldplate Mount: The VIPAC Array can be mounted on a cold plate using appropriate screws and mounting holes. This allows for better heat dissipation.
Mechanical Drawings
For detailed mechanical drawings and dimensions of each VIPAC Array variant,
please refer to the product’s respective documentation or contact technical
support.

PRODUCT OVERVIEW
The VIPAC Array is a highly flexible system of DC input, and power building blocks that can be configured with as many as four user-definable outputs on a low-profile, cold plate 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, and DC-DC converters.
Using Vicor’s VCAD configuration tool, (vicorpower.com/vcad), 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 offer the user a choice of power and mechanical options to fit most designs. Short cycle time and rapid delivery make the VIPAC Array a valuable tool for power system prototyping and development efforts as well.
For technical information refer to “Design Guide & Applications Manual for Maxi, Mini, Micro Family DC-DC Converters and Accessory Modules”
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 cold plate chassis simplifies thermal management and mounting.
Vicor’s VCAD configuration tool provides expedited part configuration, 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.

- Removable jumpers in J4 are factory-installed for local sensing. For remote sensing and redundant parallel arrays as illustrated above 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 on the -Out power bus.
- There should be one parent module, this is realized by choosing one module to be the parent and shorting the SC to –S on the other module. Units configured from the factory as paralleled will already have this configured. This should be verified by direct inspection before system integration.
- There should be one parent module, this is realized by choosing one module to be the parent and shorting the SC to –S on the other module. This is done by installing a 0Ω resistor in the space provided on the lugmate / plugmate.
OUTPUT CONNECTION OPTIONS
Please Note:
VIPACs that contain multiple modules configured as a single output (paralleled
for power or redundancy) MUST have their Outputs and Sense connected at the
load. DO NOT OPERATE A PARALLEL CONFIGURATION WITH ONLY ONE MODULE CONNECTED.
Additionally, one module must be designated as a “parent” by having all other
modules configured as “Boosters”. Boosters are created by shorting the SC pin
to –S.
