NOTE:

1.The continuous max DC output power shall not exceed 350W. +5V, +12V1, +12V2, and +3.3V output power shall not exceed 334W.

2.Ripple & noise test condition: AC 115V/230V 60/50Hz at full load

2.1 HOLD-UP TIME: 20ms (minimum)

Test Condition: 1. Full load. AC input 115V/230V, 57Hz/47Hz

2.2 LOAD TRANSIENT RESPONSE (STEP LOAD)

Step load changes of up to 20% of full load, while other loads remains constant within the rating. The load waveform shall be a square wave with the slope of the rise and fall at 1A/µsec and the frequency shall be from 10Hz to 1kHz. The DC output voltage will stay within regulation during the step load changes.

2.3 OVERSHOOT

Overshoot at turn-on shall be less than 10% of the nominal output voltage.

3.0 PROTECTION:

If the power supply is latched into shutdown stage (when OCP, OVP, OPP or short protection is working), the power supply shall return to normal operation only after the fault has been removed and should reset PS-ON for a minimum of 1 second. Then it will turn on again.

3.1 INPUT UNDER VOLTAGE

The power supply shall contain protection circuitry such that application of an input voltage below the minimum specified in Section 1.1 shall not cause any damage to the power supply.

3.2 OVER CURRENT PROTECTION

SENSE LEVEL	OVER CURRENT
12V1	17.6A min	20.8A max
12V2	19.5A min	23.4A max
+5V	33.0A min	45.0A max
+3.3V	30.8A min	42.0A max
3.3 OVER VOLTAGE PROTECTION
SENSE LEVEL	OVER VOLTAGE
12V1 & 12V2	13.3V min	14.3V max
+5V	5.7V min	6.2V max
+3.3V	3.7A min	4.1A max

3.4SHORT CIRCUIT PROTECTION All output to ground.

3.5UNDER VOLTAGE PROTECTION

SENSE LEVEL	UNDER VOLTAGE
12V1 & 12V2	9.5V min	10.5V max
+5V	4.1V min	4.47V max
+3.3V	2.55 Vmin	2.83V max

3.6 OVER TEMPERATURE

The power supply includes an over-temperature protection sensor, which can trip and shutdown the power supply at 110°C. Such an overheated condition is typically the result of internal current overloading or a cooling fan failure.

3.7 OVER LOAD PROTECTION

Overload currents to output rail will cause the output trip before they reach or exceed 110% ~ 140% for protection, the overload currents should be ramped at a minimum rate of 10A/s starting from full load.
