Product Highlights

If you’re looking for the convenience
of a complete, low profile, agency­approved switching power supply, look
no further. The FlatPAC combines Vicor’s
workhorse VI-200 family of DC-DC
converters with a modular package and
front-end subassembly to provide from
50 to 600 W of output power from one
to three outputs.

A flat plate heat sink for use in conduction
cooled applications may be specified as an
alternate to the standard finned version by
adding “CC” to the end of the model
number.

Vicor’s FlatPAC is also available with a
current controlled output using BatMod
converter modules of 12, 24, or 48 Vdc
outputs. This option is specified by
appending “BM” or “BC” (for conduction
cooled versions) to the end of the FlatPAC
model number.

Mixing VI-200 and BatMods in a single
FlatPAC is not permissible.

The FlatPAC’s contemporary design
allows us to configure your order quickly
and provide rapid turnaround on standard
models. It is truly a complete power
solution, enabling you to spend more time
designing your system and less time
worrying about how to power it.

Substitute VE– for VI– for RoHS compliant versions
