FlatPAC™
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 600W of output power from one to three outputs.
A flat plate heatsink 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 48Vdc outputs. This option is specified by appending “BM” or “BC” (for conduction cooled versions) to the end of the FlatPAC model number.
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.
