Mini MegaPAC
TM
AC-DC Switcher
USER GUIDE | UG:110

Overview
The Mini MegaPAC AC-DC switcher allows users to instantly configure high efficiency,
off-line power supplies that operate on either 115 or 230 Vac (47-500 Hz),
or 260-380 Vdc. Although small in size, (3.4"H x 6.0"W x 9.5”L), (85,8 x 153,4 x 241,3 mm),
the Mini MegaPAC provides up to 1,000 W of output power. The chassis has five slots
and can provide up to ten isolated outputs.
A complete power supply is configured at the factory by selecting and inserting up
to five same length slide-in output assemblies called ConverterPACs. ConverterPACs
incorporate one or two VI-200/VI-J00 and/or Maxi Vicor DC-DC converters and are
available in a wide array of output voltages 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. For detailed information about the ConverterPACs, refer
to the ConverterPAC data sheets. The ConverterPACs used in the Mini MegaPAC use VE-
2xx and VE-Jxx modules. In addition, there is a four output model called a FlexPAC that
uses discrete circuits to support low power needs.
Manufactured at Vicor, 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 ConverterPAC assembly with one of the same length and has the desired voltage
power rating. For additional flexibility, ConverterPACs can be connected in parallel to
increase output power (booster ConverterPACs), or in series for higher voltages (total
output voltage should not exceed 400 V). 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. Using
the VSPOC configurator tool available on
, anybody can now
configure a Mini MegaPAC (and other Vicor power supplies) online.
