120Watts DC-DC ATX Power Supply

Size: 44.5mm(L) * 20mm(W) * 30mm (H) (1U compliant)

Weight: 57gramms, including cable harness, 27 grams without cable harness.

DC-Jack: Female, panel mount, 2.5*5.5*10 mm.

 

Connectors

Molex 39-01-2200, two 3.5?? drive power connector, 1 floppy. P4-12V 4

pin header adapter sold separately.

 

Overload protection

Over load protection will be effected when either of the loads (+5V &

+3.3V) exceeds > 200% Max Load.

 

Turn-on Delay

After turning on, at least 20 ms will be needed for the rise of +5VSB

output voltage (measured from 10% to 95%) to reach its peak.

 

Remote ON/OFF control

Logic level is LOW -Output voltage is enabled (PS_ON pin)

Logic level is HIGH -Output voltage is disabled (PS_ON pin)

 

Operating environment: Temperature: -20 to 85 degree centigrade.

Relative Humidity: 10 to 90 percent, non-condensing.

 

Efficiency, MTBF: 95%. MTBF=100K hours at 55Celsius.

At max load, forced air ventilation is required. For fanless operation de-rate the output of the 3.3 and 5V rails by ~20%. Peak load should not exceed 60 seconds.
