13.3.2.7 Power Recovery
The power supply shall recover automatically after an AC power failure. AC power failure is
defined to be any loss of AC power that exceeds the dropout criteria.
13.3.3 Efficiency
The following table provides the required minimum efficiency level at various loading conditions.
These are provided at three different load levels; 100%, 50%, 20%, and 10%. Output shall be
loaded according to the proportional loading method defined by 80 Plus in Generalized Internal
Power Supply Efficiency Testing Protocol Rev. 6.4.3. This is posted at
http://efficientpowersupplies.epri.com/methods.asp.
