Product Highlights
The MI-ComPAC is a complete single, dual, or triple output DC-DC power supply that delivers up to 300W from inputs of 28Vdc or 270Vdc.
The MI-ComPAC meets the conducted emissions and conducted susceptibility specifications of MIL-STD-461C/D/E and offers complete input transient, surge, and spike protection to the most severe levels of MIL-STD-1275A, 704A.
Reverse polarity protection and over/undervoltage lockout provide additional safeguards against potentially damaging line conditions. The MI-ComPAC also features a master disable.
