3.5.1 under-voltage protection In the event of an under-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 : 4.2V (minimum) +3.3V : 2.8V (minimum) +12V : 10.3V (minimum) 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.
3.7 OUTPUT OVERSHOOT/UNDERSHOOT No output voltage shall overshoot / undershoot or generate spikes at turn-on or turn-off, during momentary power loss, output short, or realistic input voltage or output load changes, Overshoot/undershoot is defined as any output that exceeds the voltage tolerance plus or minus an additional 5%. All outputs shall be measured with minimum load (COND.3) +3.3V +5V +12V1 +12V2 -12V +5VSB 3.8 Overshoot 3.63V 5.5V 13.2V 13.2V -13.8V 5.5V Undershoot 2.97V 4.5V 10.8V 10.8V -10.

The transient load slew rate is = 1.0 A/µs.
3.12 Capacitive Load The power supply should be able to power up and operate normally with the following capacitances simultaneously present on the DC outputs. This capacitive loading should be used to check all of function test, but without hold-up time.
