3.3 Efficiency
The following table provides the required minimum efficiency level at various loading
conditions. These are provided at three different load levels; 100%, 50%, and 20%.
Efficiency was tested over an AC input voltage range of 115 VAC to 220 VAC.

3.4 AC Input Voltage Specification
The power supply operates within all specified limits over input voltage range shown in the
following table. Harmonic distortion of up to 10% THD will 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 85 VAC +/-4
VAC. Application of an input voltage below 85 VAC will not cause damage to the power
supply, including a fuse blow.
