AC Input Voltage Specification
The power supply must operate within all specified limits over the following input voltage range.
Harmonic distortion of up to 10% of the rated line voltage must not cause the power supply to
go out of specified limits. Application of an input voltage below 85VAC must not cause damage
to the power supply, including a blown fuse.

Notes:
1. Maximum input current at low input voltage range must be measured at 90VAC, at max load.
2. Maximum input current at high input voltage range must be measured at 180VAC, at max load.
3. This requirement is not to be used for determining agency input current markings.
