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.

Output Filters
- MIL-COTS MicroRAM – Output Ripple Attenuator Module – The MicroRAM combines both active and passive filtering to achieve greater than 40 dB of noise attenuation from over a range of 3 – 30 Vdc.
- MI-RAM – Ripple Attenuator Module- MI-RAM may be connected to MI-200 or MI-J00 converters with output voltages from 5 – 50 Volts, to limit total output noise to less than 3 mV peak-to-peak at loads up to 20 Amps.
