3.2 AC Input Specification
3.2.1 Input Voltage And Frequency
The power supply must operate within all specified limits over the following input voltage range.
Harmonic distortion of up to 10% THD must not cause the power supply to go out of specific
limits. The power supply shall be capable of start-up (power-on) with full rated power load, at
line voltage as low as 90VAC.

Note:
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.
3.2.2 AC input Power Factor
The power supply must meet the power factor requirements stated in the Energy Star
®
Program
Requirements for Computer Servers. These requirements are stated below.
