Description

The MI-ComPAC is a complete single, dual, or triple output DC-DC power supply that delivers up to 300 watts from inputs of 28 or 270 Vdc. Each unit incorporates one, two, or three component-level Vicor MI-200 family DC-DC converters.

The MI-ComPAC meets the conducted emissions and 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/B/D, MIL-STD-704A-F, and DO-160E. Reverse polarity protection and over/undervoltage lockout provide additional safeguards against potentially damaging line conditions. The MI-ComPAC also features a logic enable/disable.
