Manufactured at Vicor, the entire family of MegaPAC power supplies is completely
user-configurable. If output requirements change, i.e., more power or a dierent
output voltage is needed, upgrading is easy: simply unlock a single screw and replace
the slide-in ConverterPAC assembly with one that is 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 le of
the boosters when looking at the output end of the supply. A user-friendly interface
provides control and output sequencing capability (see page 30 for more information
about this capability), in addition to useful status indicators. Please consult our
Applications Engineering Department if you have other special requirements.
