    ● 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 oscilloscope 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, under voltage, 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

     

     

    6. Time SEQ Test

     

    SECC Switching Mode Power Supply

     

    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

     

     

    11. Environment

     

    11.1 Use environment temperature: 5℃ to +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%
