MPD-425C

250W DC-DC Power Supply

Input Range: 19~32VDC

*Input Voltage: 19~32VDC

*Input Current: Max. 8A at 24VDC

*Inrush Current: Does not exceed 10A at 24VDC input, cold

*Ripple and Noise: < +/-1% peak to peak ripple and noise for

each output

*Line Regulation: < +/-1% at rated load with +/-10% change

in input voltage
