    2. AC Input


    1.1 Input voltage

    AC Input    Min Normal Max      Unit

    Voltage 95  110      135      VAC rms

    180      220      264      VAC rms

    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 oscilloscope bandwidth set at 20MHz with co-axial probe.

    ● Regulation load must within 30% to 70% of maximum load.




    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.


    120-160% of maximum power


    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%
