120Watts DC-DC ATX Power Supply
Power Ratings (Max Load = 140 Watts)
Output Max Load (A) Peak Load (A) Regulation%
5V 6A 8A +/-1.5%
3.3V 6A 8A +/-1.5%
5VSB 1.5A 2A +/-1.5%
-12V 0.05A 0.2A +/-1.5%
12V 7A 10A Switched input
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.
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.
