DC-DC Switcher
USER GUIDE | UG:123
Overview
The DC MegaPAC DC-DC switcher allows users to instantly configure high efficiency power supplies.
Although small in size (6.0 x 11.7 x 3.4in) [153,4 x 296,7 x 85,8mm]), the DC MegaPAC provides up to
1600W of output power with up to 16 isolated outputs.
A complete power supply is configured by selecting and inserting up to eight slide-in output assemblies
called “ConverterPACs
™
.” ConverterPACs incorporate one or two Vicor DC-DC converters and are
available in a wide array of outputs and power levels. The net result is a power supply that offers the
advantages of a custom supply, but is assembled from standard and modular building blocks.
The entire family of MegaPAC power supplies is completely user-configurable. If output requirements
change, i.e., more power or a different output voltage is needed, upgrading is easy: simply unlock
a single screw and replace the slide-in ModuPAC
™
assembly with one that has the desired rating.
For additional flexibility, ModuPACs can be connected in parallel to increase output power (booster
ModuPACs), or in series for higher voltages. The driver is to the left of the boosters when looking at the
output end of the supply. A user-friendly interface provides control and output sequencing capability, in
addition to useful status indicators. Please consult our Applications Engineering Department if you have
other special requirements.
