Product Highlights
Vicor’s MegaMod and MegaMod Jr.
Families of single, dual and triple output
DC-DC converters provide power system
designers with cost effective, high
performance, off-the-shelf solutions to
applications that might otherwise require a
custom supply.
Incorporating standard VI-200 or VI-J00
Family converters in rugged, chassis mount
packages, MegaMod and MegaMod Jr.’s
can be ordered with single, dual or triple
outputs, having a combined output power
of up to 600W. Totally isolated outputs
eliminate efficiency penalties and output
interaction problems.
