Autoranging MegaPAC

AC-DC Switcher

USER GUIDE | UG:106

June 2013

Overview

The Autoranging MegaPAC AC-DC switcher allows users to instantly conﬁgure high

eciency, o-line power supplies that operate on either 115 or 230 Vac (47-500 Hz), or

260-380 Vdc. The Autoranging MegaPAC provides up to 1,600 W of output power with a

power density of 6.6 W per cubic inch. The chassis has 8 slots and can provide up to 16

isolated outputs. Its dimensions are 3.4"H x 6.0"W x 11.9"L (86,4 x 152,4 x 302,3).

A complete power supply is conﬁgured at the factory by selecting and inserting up to

eight same length slide-in output assemblies called ConverterPACs. ConverterPACs

incorporate one or two VI-200/VI-J00 and/or Maxi Vicor DC to DC converters and are

available in a wide array of output voltage and power levels. The net result is a power

supply that oers the advantages of a custom supply, but is assembled from standard

and modular building blocks. For detailed information about ConverterPACs, refer

to the ConverterPAC information sheets. Currently, the ConverterPACs used in the

Autoranging MegaPAC only use VI-200/VI-J00 Vicor DC to DC converters.

Refer to page 6 for a brief overview of the ConverterPACs used.

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 a same length ConverterPAC and one that

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, in addition to useful status

indicators. Please consult our Applications Engineering Department if you have other

special requirements.
