5.5 Electrical Requirements
5.5.1 Efficiency
The power supply has a minimum efficiency of 65% to its DC output pins at maximum load cur-
rents and at rated nominal input voltages and frequencies.
The power supply has a minimum effi-
ciency of 70% to its DC output pins at maximum load currents when the input voltage is higher
than 180 Vac.
5.5.2 AC Input Voltage Specification
5.5.3 AC Input Voltage Ranges
The nominal input voltage ranges specified in AC volts root-mean-square (rms)# are 100-120
and 200-240 Vac. The power supply incorporates a universal power input with active power fac-
tor correction, which reduces line harmonics in accordance with EN61000-3-2 and JEIDA MITI
standards. The ratings are marked on the supply labels as referenced in Table 5-2: Input Voltage
Requirements
and Section Internal System Marking.
† Proper values to be determined by the power supply manufacturer. Correct values are to be printed on the
internal system label shown in Figure 5-3: Internal Label.
5.5.3.1 AC 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 com-
plete cycle of AC input power frequency (i.e., 20 milliseconds at 50 Hz) or less, will not cause any
out-of-regulation conditions, such as overshoot or undershoot, nor will it cause any nuisance trips
of any of the power supply protection circuits.
5.5.3.2 AC 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-
