DC MegaPAC™
DC-DC Switcher
Overview
The DC MegaPAC DC-DC switcher allows users to instantly configure high efficiency power supplies. Although
small in size (3.4"H x 6.0"W x 11.7"L), (85,8mm x 153,4mm x 296,7mm), 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 to 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.
