5.5Electrical Requirements
5.5.1Efficiency
The power supply has a minimum efficiency of 65% to its DC output pins at maximum load currents and at rated nominal input voltages and frequencies. The power supply has a minimum efficiency of 70% to its DC output pins at maximum load currents when the input voltage is higher than 180 Vac.

5.5.3.1AC Line Dropout
AC line dropout condition is a transient condition defined when the line voltage input to the power supply drops to 0 volts. AC line dropout will not damage the power supply under any load condi- tions. While operating at full load, an AC line dropout condition with a period equivalent to a complete cycle of AC input power frequency (i.e., 20 milliseconds at 50 Hz) or less, will not cause any
5.5.3.2AC Line Fuse
Both the LINE and NEUTRAL AC inputs are fused. AC line fusing is compliant with all safety agency requirements. AC inrush current will not cause the AC line fuses to blow under any condi-
