3.4 Protection
The power supply itself is designed with short circuit, over voltage, over power
and over current protection functions described as below:
3.4.1 Short Circuit Protection
A short circuit on any DC output will cause the power to latch. The power
supply will withstand a continuous short circuit to the output without damage
or overseers to the unit. The +5V can be shorted indefinitely and will recover
SB
automatically when the short is removed.

3.2 Active Power Factor Correction
Active power factor correction (the advance technology most used in high power
SMPS) used a per-regulator before the main PWM convert circuit, applied the
current feedback technology. Regulated current drawing flow AC sinusoidal wave.
Therefore, the THD less than 5 percent,and the power factor increase to 0.99 or higher.
This method of PFC knows as Active Power Factor Correction because applied active
components and circuit inside. It can provide high power factor(up to 0.95-1),can
operate in world wide input range(100-240VAC).An intelligent solution for high regulation,
high power density power designs.
3.4.2 Over Voltage Protection
The power supply over voltage protection shall be locally sensed. The power
supply shall shutdown and latch off after an over voltage condition occurs. This
latch shall be cleared by toggling the PSON # signal or by an AC power
