manual

2 The power efficiency shall be 78% at ATE test at full load@115Vac input.
4. Protection Circuits
Protection circuits inside the power supply shall cause only the power supply’s main outputs to shutdown. If
the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15 sec and a PSON
#
cycle HIGH for 1 sec must be able to restart the power supply.
4.1 Over Current Protection (OCP)
The power supply shall have current limit to prevent the +5V, +3.3V, and +12V outputs from exceeding the
values shown in Table-Over Current Protection. The power supply shall latch off if the current exceeds the
limit.
Table 10: Over Current Protection
Voltage Minimum Maximum Shutdown Mode
+3.3V 33A 45A Latch Off
ffO hctaL A06 A44 V5+
+12V 75A 102A Latch Off
4.2 Over Voltage Protection (OVP)
The power supply shall shut down and latch off after an over voltage conditions occurs. 5Vsb will be
auto-recovered after removing OVP limit.
Table 11: Over Voltage Protection
Voltage Minimum Maximum Shutdown Mode
+5V +5.7V +6.5V Latch Off
+3.3V +3.9V +4.5V Latch Off
+12V +13.3V +14.5V Latch Off
+5VSB +5.7V +6.5V Latch Off
4.3 Short Circuit Protection
The power supply shall shut down in latch off mode when the output voltage is short circuit.
4.4 No Load Operation
No damage or hazardous condition should occur with all the DC output connectors disconnected from the
load. The power supply may latch into the shutdown state
4.5 Over Temperature Protection (OTP)
The power supply will shut down i when an over temperature condition occurs; no damage shall be caused.
