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).

2.3.2 Definition
The ripple voltage of the outputs shall be measured at the pins of the output connector
when terminated in the load impedance specified in figure 1. Ripple and noise are
measured at the connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic
capacitor to simulate system loading. Ripple shall be measured under any condition of
line voltage, output load, line frequency,operation temperature.
