4.1.2.3 AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range, as
shown in the following table. Harmonic distortion of up to 10% of rated AC input voltage will not
cause the power supply to go out of specified limits. The power supply powers off at or below
75 VAC +/-5 VAC range. The power supply starts up at or above 85 VAC +/-4VAC. Application
of an input voltage below 85 VAC does not cause damage to the power supply, including a fuse
blow.

Notes:
1 Maximum input current at low input voltage range should be measured at 90Vac at max load.
2 Maximum input current at high input voltage range should be measured at 180VAC at max load.
3 This is not to be used for determining agency input current markings.
4 Maximum rated input current is measured at 100 VAC and 200 VAC.
4.1.2.4 AC Line Transient Specification
AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are
also commonly referred to as “brownout” and defined as AC line voltage drops below nominal
voltage conditions. “Surge” is defined as AC line voltage rises above nominal voltage conditions.
The power supply meets requirements under the following AC line sag and surge conditions.
