1. Function Description This power supply is designed for personal computer. There are six DCoutputs: +5V, -5V, +12V, -12V, +3.3V＆+5V SB , and it provides power to all computer systems and peripherals with maximum protection.
. Input Requirements 3.1. Input Voltage The power supply shall be operated at the range below: Input Range 100~120Vac 200~240Vac Volt Selector Set 115 230 3.2. Frequency The input frequency range is from 47Hz to 63Hz. 3.3. Inrush Current The max. inrush current is 45A for 115Vac and 70A for 230Vac, respectively. 3.3.1. Cold Start Conditions 115/230Vac, full load, ambient 25degree C Limits NO component over stress or damage should occur to the power supply. Input fuse shall not blow. 3.3.2.

If ambient temperature is under 20 or over 30, the AC input should be nominal input. 4.6.

Hold Up Time(T5) MIN. 14 Units ms The test environment is 25 degree C & full load @ nominal input. 4.13. Power Fail Signal (T6) Power good signal shall go to a down level 1ms before +5V output voltage falls below the regulation limits during PS-ON signal MIN. 1 Units ms 5. Protections 5.1.
5.2. Short Circuit Protection A short circuit placed on any output shall cause no damage or the power supply shall shutdown. (The contact resistance is 0.05 ohm when outputs short circuit.) 5.3. Protection Reset When the power supply latches into shutdown condition due to a fault on an output, the protection shall reset after the fault has been removed. Use remote on/off control or recycle the AC power again for a typical of 3 seconds. 5.4.
Power connector starts to rotate to pull the inner heat outside . When power supply inner temperature decreases below 60 degree C, the fan stops, the yellow led turns off and the green turns on again. In this way to achieve balance between heat and noise, and realize the most possible silence of the system under precondition the system works properly. 6.3. Humidity (none condensing) Operation: 20% to 85% RH Storage: 10% to 95% RH 6.4. Altitude Operation: to 10,000 ft Storage: to 50,000 ft 7.
11.3. Don't attempt to remove the front panel heat sink at any time, or it may result in a system shutdown. 1 1 . 4 . H I G H TE M PE RA T URE !
