AC Input Voltage
The power supply must operate within all specified limits over the following input voltage range,
shown in table below. 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 shall power off if the AC
input is less than 75VAC +/-5VAC range. The power supply shall start up if the AC input is
greater than 85VAC +/-4VAC. Application of an input voltage below 85VAC shall 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.

AC Line Transient Specification
AC line transient conditions shall be 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 shall meet the requirements under the following AC line sag and surge
conditions.
