CONFIGURATION GUIDE

PRODUCT OVERVIEW

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 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 most designs. Short cycle time and rapid delivery make 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 models 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.

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.

Factory installed Mini/Maxi LugMate

• 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 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 paralled will already have this configured. This should be verified by direct inspection prior to 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.

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. Additionally one module must be designated as “parent” by having all other modules configured as “Boosters”. Boosters are created by shorting the SC pin to -S.

Mounting Options

1. VIPAC Array with external, user supplied heat sink.
2. VIPAC Array mounted to cabinet wall with thermal compound between VIPAC Array and cabinet wall.
3. VIPAC Array mounted to custom thermal interface.
