2.4.5 AC Input Voltage Requirements
2.4.5.1 AC Input Voltage Specification
The power supply operates within all specified limits over the 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. 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.

1. Maximum input current at low input voltage range is measured at 90VAC, at max load.
2. Maximum input current at high input voltage range is measured at 180VAC, at max load.
3. This requirement is not used for determining agency input current markings.
2.4.5.2 AC Line Transient Specification
AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are
also commonly referred to as “brownout,” and are defined as AC line voltage drops below
nominal voltage conditions. “Surge” is defined as AC line voltage rises above nominal voltage
conditions.
