The power supply meets UL enclosure requirements for temperature rise limits. All sides of the 
power supply, with exception of the air exhaust side, must be classified as “Handle, knobs, 
grips, etc. held for short periods of time only”. 

2.2.2 

AC Input Voltage Requirements 

The power supply operates within all specified limits over the 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 will 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 will not cause damage to the power supply, 
including a fuse blow.

AC Inlet Connector 

The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 15A/250VAC. 

2.2.2.2 

AC Line Transient Specification 

AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are 
also commonly referred to as “brownout”; these conditions will be defined as the AC line voltage 
dropping below nominal voltage conditions. “Surge” will be defined to refer to conditions when 
the AC line voltage rises above nominal voltage. 

The power supply meets the requirements under the following AC line sag and surge conditions.
