REMOTE ON/OFF CONTROL

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 enable.

As logic level is high, outputs voltage were disable.

Note: 1. Logic high level :3.50-5.25V while sourcing 0.4mA maximum.

         2. Logic low level : 0-0.5V while sinking 1.5mA maximum.

         3. Rise Time : 2ms maximum (10%-90%).

3.3

OUTPUT VOLTAGE HOLD-UP TIME

10.0 mS minimum : at 230V / 50 Hz.

3.4 OPERATION AT NO LOAD

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 +4.5 & +6.5Vdc and the power supply may shutdown and require

by remote-control or remove AC power restart.

PROTECTION

OVER-VOLTAGE

PROTECTION

3 .5.1

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: 4.6V(maximum)

+12V1DC : 15.5V(maximum)

+12V2DC : 15.5V(maximum)

3 .5.2

O V E R -CURRENT

PROTECTION

There shall be protection from an output over-current event. The supply may shutdown

form such an event and require power-on restart. Testing consists of application of the

listed over-current value with maximum load on all other outputs.

Over-current test values: (maximum load)

      +3.3V :65A maximum

      +5V:50A maximum

      +12V1DC :21A maximum

      +12V2DC :27A maximum

3 .5.3

S H O R T -C U R R E N T P R O T E C T I O N

A short circuit at any output shall cause no damage to the power supply nor blow the

primary fuse. The supply may shut down in the event of a short circuit and require

power-on restart. A short circuit consists of application of a test resistance of less than

0.05 ohms at each output with maximum load on all outputs.

3.6 OUTPUT RISETIME

 The cold-start enable output voltage risetime of all outputs shall be

 measured with maximum load on all outputs.

 risetime : +3.3V20mS (maximum)

3.7 OUTPUT OVERSHOOT

No output voltage shall overshoot or generate spikes at turn-on or turn-off,

during momentary power loss, output short, or realistic input voltage or

output load changes, Overshoot is defined as any output that exceeds the

voltage tolerance plus or minus an additional 5%.

3.8

EFFICIENCY

Overall efficiency must be 65% minimum measured at normal AC mains

voltage and frequency with maximum loads on all outputs.
