Frequency 50 --- 60 Hz
1.2 Max input current 3A (input 220V)/6A(input110V) 
1.3 Max surge current 60A (220V, cold start at room temperature)

3. Power Efficiency

3.1 minimum 70 % (Input 220V/50Hz, full load power rating)

4. DC Output

Output voltage, current, ripple and noise
Voltage +5V +12V +3.3V -12V +5VSB
max load 12A 12A 7A 0.6A 2A
Full load 9A 9A 5A 0.5A 1.5A
Min load 1.0A 0.5A 0.5A 0.1A 0.1A
Regulation ±5% ±5% ±5% ±10% ±5%
Ripple 50mV 120mV 50mV 200mV 50mV
Noise 100mV 240mV 100mV 300mV 100mV
Power supply works continuously, the DC output total power with no more than 180W, +3.3V and +5V sum of output power maximum 90 W.
A 0.1uF ceramic disk capacitor & 10uF electrolytic (low ESR) capacitor should be put across the output terminals during ripple & noise measure. The oscillo-scope bandwidth set at 20MHz with co-axial probe.
Regulation load must within 30% to 70% of maximum load.
AMBIENT TEMPERATURE 25°C.

5. Protection

NOTE: due to overpower, overvoltage, undervoltage, short-circuit protection movement, the power locked in shut off condition, only when these reasons remove, remote control switch at least 1 second reduction (or at least reset shut the power supply after 10 seconds), power supply can restart.
5.1Short-circuit protection: the power supply will be automatic protection and close the output no matter which output terminal short circuit.
5.2 OVER LOAD PROTECTION
120-160% of maximum power.
5.3 SHORT CIRCUIT PROTECTION
All output to ground.

6. Time SEQ Test

6.1 POWER GOOD signal delay time (T3): 100ms ≤T3≤500ms
6.2 POWER GOOD signal rise time (T4): T4≤10ms
6.3 Hold-up Time (T5): T5≥16ms
6.4 POWER FALL signal delay time (T6): T6≥1ms

7. Remote Switch Control

7.1 DC output (except for +5Vsb) can be controlled by logic circuit
7.2 Logic circuit controls power supply on and off
Input low voltage 0~0.8V Power supply turn ON
Input High Voltage 2~5.25V Power supply turn OFF

8. Auxiliary Output +5Vsb

Power supply output a rated current value for 2A +5V boost voltage, the output voltage is only controlled by the input voltage.

9. Hi-pot Test

Input to earth: AC 1500V keep 3.0 seconds, the biggest leakage current 10mA

10. Earth Continuity Test

Under 24A current test condition, resistance≤100mΩ
