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

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.

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
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.

3.7 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.
