420-Watt Power Supply Requirements
Input Requirements
The following represent the input requirements of the 420-watt power supply:
•
Maximum waveform harmonic distortion shall be less than 5%. The
power supply must operate above frequency with both 100~120/200~240
VRMS input voltage ranges.
•
The power supply must operate over both voltage ranges with an outside
switch.
The table below shows the 420-watt power supply input requirements.
