2.1.4 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% THD must not cause the power
supply to go out of specified limits. The power supply does power off if the AC input is less than
75VAC +/-5VAC range. The power supply starts up if the AC input is greater than 85VAC +/-
4VAC. Application of an input voltage below 85VAC does not cause damage to the power
supply, including a fuse blow.

2.1.4.1 AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 15A/250VAC.
2.1.4.2 Efficiency
The power supply has an efficiency of 68.5% at maximum load and over the specified AC
voltage.
2.1.4.3 AC Line Dropout/Holdup
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 of one cycle or less the power supply meets
dynamic voltage regulation requirements over the rated load. An AC line dropout of one cycle or
