2.5.4 AC Input Requirements
The power supply operates within all specified limits over the following input voltage range,
shown in the following table. Harmonic distortion of up to 10% of the rated line voltage must not
cause the power supply to go out of specified limits. If the AC input is less than 75VAC +/-5VAC
range, the power supply does power off. If the AC input is greater than 85VAC, the power
supply starts up. Application of an input voltage below 85VAC does not cause damage to the
power supply, including a fuse blow.

Notes:
1 Maximum input current at low input voltage range shall be measured at 90VAC, at max load.
2 Maximum input current at high input voltage range shall be measured at 180VAC, at max load.
3 This requirement is not to be used for determining agency input current markings.
2.5.4.1 AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 10A / 250VAC.
2.5.4.2 Efficiency (80+ Bronze)
The following table provides the required minimum efficiency level at various loading conditions.
These are provided at three different load levels; 100%, 50% and 20%. Output is loaded
according to the proportional loading method defined by 80 Plus. Efficiency is tested per 80 Plus
requirement.

2.5.4.3 AC Line Dropout / Holdup
Loading Holdup time
75% 20msec
An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC
line for any length of time. During an AC dropout the power supply meets dynamic voltage
