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 power supply will shutdown.  
When the power supply temperature drops to within specified limits, the power supply shall 
restore power automatically, while the 5 Vsb remains constantly on. The OTP trip level shall 
have a minimum of 4

°C of ambient temperature hysteresis, so that the power supply will not 

oscillate on and off due to a temperature recovery condition.  The power supply shall alert the 
system of the OTP condition via the power supply FAIL signal and the PWR LED. 

The following table defines power and current ratings for this 750W continuous (860W pk) 
power supply in 1+0 or 1+1 redundant configuration.  The combined output power of both 
outputs shall not exceed the rated output power.  The power supply must meet both static and 
dynamic voltage regulation requirements for the minimum loading conditions.  Also, the power 
supply shall be able to supply the listed peak currents and power for a minimum of 10 seconds.  
Outputs are not required to be peak loaded simultaneously.

12V x 62A = 744W max 

5V x 3A = 15W max 

12V x 70A = 840W pk 

5V x 5A = 25W pk 

 

The 5Vsb output shall be present when an AC input greater than the power supply turn-on AC 
voltage is applied. Applying an external 5.25V to 5Vsb shall not cause the power supply to shut 
down or exceed operating limits.  When the external voltage is removed the voltage shall return 
to the power supplies operating voltage without exceeding the dynamic voltage limits.
