Product Highlights
If you're looking for the convenience
of a complete, low profile, agency-
approved 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.
