Product Description
The FlatPAC family of user-definable offline power supplies provides a complete
power solution that incorporates one, two, or three standard Vicor DC-DC
converters and a front-end subassembly in a modular package. FlatPAC is available
with one, two, or three outputs and total output ratings of 50–600 W. These power
supplies feature an autoranging input, which automatically senses the input line
voltage and sets the power supply’s input range accordingly. FlatPAC’s unique
modular design accommodates over 10,000 different configurations.
FlatPAC power supplies that contain BatMod current source modules instead of
VI-200 converters are indicated by the suffix -BM following the FlatPAC part
number. BatMod converters provide a programmable output current, rather than a
regulated output voltage. Consequently, the output supervisory terminal functions
differ on FlatPACs with BatMod modules.

FlatPAC units are shipped with pins 11-12
and 14-15 connected via jumper plugs
(Vicor P/N 02589) for
local sense.
For
remote sense,
remove these connections
and connect pins 10-12 and 14-16, as
shown in the Output Sense and Trim
drawing on page 3.
