2.4 Inrush Current
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).
2.5 Efficiency
SST-ST50F-ES230 provides an efficiency of >80% when measured at full load
under 230V/50Hz condition.
