Product Description
The MI-ComPAC is a complete single,
dual, or triple output DC-DC power supply
that delivers up to 300W from inputs
of 28 or 270V
DC
.
The MI-ComPAC meets the conducted
emissions and conducted susceptibility
specifications of MIL-STD-461C/D/E and
designed to meet the input transient,
surge, and spike protection to the
most severe levels of MIL-STD-1275,
F
MIL-STD-704 and DO-160E.
Over/undervoltage lockout provides an
additional safeguard against potentially
damaging line conditions. The MI-ComPAC
also features a master disable.

• Thermal impedance, chassis-to-air, is provided for 1-up, 2-up and 3-up MI-ComPAC package configurations as a function of airflow.
• Case temperature = (total power dissipated • thermal impedance) + ambient temperature.
• Watts dissipated per output = (output power ÷ efficiency) – output power.
