STATUS 

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 interruption.  Table 19 contains the over voltage limits.  The values are measured at the output of the 
power supply’s connectors.  The voltage shall never exceed the maximum levels when measured at the power 
pins of the power supply connector during any single point of fail.  The voltage shall never trip any lower than the 
minimum levels when measured at the power pins of the power supply connector.

STATUS 

The power supply will be protected against over temperature conditions caused by loss of fan cooling or 
excessive ambient temperature. In an OTP condition the PSU will shutdown.  When the power supply 
temperature drops to within specified limits, the power supply shall restore power automatically.  The OTP circuit 
must have built in hysteresis such that the power supply will not oscillate on and off due to temperature recovering 
condition.  The OTP trip level shall have a minimum of 4 

°

C of ambient temperature hysteresis.
