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.
Inputs:
28Vdc per MIL-STD-704A, MIL-STD-1275A
270Vdc per MIL-STD-704D/E
Outputs: 1 to 3, 2 to 48Vdc

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