MegaMod™ / MegaMod™ Jr.
Chassis-Mount DC-DC Converters



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. MegaMods provide a chassis-mount alternative to board-mounted power supplies. MegaMod and MegaMod Jr.'s can be ordered with single, dual or triple outputs, having a combined output power of up to 600 W.

Input Voltages   10 – 400 VDC
Output Voltage   2 – 95 VDC
Output Power   25 –  600 W
