Power factor correction (PF)>0.9 at full load.
1.2 Inrush current regulation
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 (Top). The peak inrush current shall be less than the ratings
of its critical components (including input fuse, bulk rectifiers, and surge limiting device).
