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.

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.

5.1 Short-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.

 

6Time SEQ Test

6.1 POWER GOOD signal delay time (T3): 100ms T3500ms
6.2 POWER GOOD signal rise time (T4): T410ms
6.3 Hold-up Time (T5): T516ms
6.4 POWER FALL signal delay time (T6): T61ms
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, resistance100mΩ
11.  Environment
11.1   Use environment temperature: 5to +40
11.2   Use environment relative humidity: 20% to 85%
11.3   Storage environment temperature: -40 to +70
11.4   Storage conditions relative humidity: 10% to 90%
