ATX DC-DC Converter Series
Input Requirements: 12-25V un-regulated, min=2A, max=10A (load 
dependent). 
Max Input Voltage supported by TVS clamp=26.5V. NOTE: Above 
26.5V, the TVS protection diode will clamp and burn the input fuse.

Weight: 70gramms, including cable harness, 35 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. 
Overload protection
Over load protection will be effected when either of the loads (+5V & 
+3.3V) exceeds 140% Max Load.
Turn-on Delay
After turning on, at least 10 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: -40 to 65 degree centigrade. 
NOTE: Unit temperature can reach up to 85C on the surface.
Relative Humidity: 10 to 90 percent, non-condensing.
