* The power supply must operate at above frequency with 103.5 - 253VACrms 
   input voltage range.
The power supply must meet inrush requirements for any rated AC voltage, 
during turn on at any phase of AC voltage, during a single cycle AC dropout 
condition, during repetitive ON/OFF cycling of AC, and over the specified 
temperature range. The peak inrush current shall be less than the ratings of its 
critical components (including input fuse, bulk rectifiers,  and surge limiting device).
