3.2 REMOTE ON/OFF CONTROL
3.3 OUTPUT VOLTAGE HOLD-UP TIME
3.4 OPERATION AT NO LOAD
3.5 PROTECTION
The power supply shall accept a logic open collector level which will disable/ enable all
the output voltage (exclude + 5V standby). As logic level is low, outputs voltage were
enabled. As logic level is high, outputs voltage were disabled.
Note: 1. Logic high level: 2.0-5.25V while sourcing 0.2mA maximum.
2. Logic low level: 0-0.5V while sinking 1.6mA maximum.
3. Rise Time: 15ms maximum (10%-90%).
The power supply shall be capable of being operated with no load on any or all outputs
without damage. For no load on +3.3V & +5V, the output shall not exceed +4.3V & +6.5Vdc
and the power supply may shutdown and require by remote-control or remove AC power
restart.
3.5.1 Over-voltage protection
In the event of an over-voltage condition on +3.3 & +5Vdc &+12V
the power supply shall shutdown and require remote control or
remove the AC mains input to reset the system.
+5V : 6.5V (maximum)
+3.3V : 4.3V (maximum)
+12V : 15.5V (maximum)
3.5.2 OVER- CURRENT PROTECTION
There shall be protection from an output over-current event.
The PSU may shutdown form such an event and require power-on
restart.
The overload currents should be ramped at a minimum rate of
10 A/s starting from full load.
Over-current test values:
16.0 mS minimum : at 115V / 60 Hz. (LOAD COND.8)
