Product Highlights
Vicor’s Mega Module and Mega
Module 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, Mega Module
and Mega Module 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.
