2.3 Max. Input AC 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).

2.4 Inrush Current

ST50F-ESB, ST40F-ESB provides an efficiency of 82% when measured at full load under 115V/60Hz

condition.

SST-ST50F-ESB

NOTE:

Noise test should be measured with 20 MHz bandwidth frequency oscilloscope. The output terminal

shall add a tantalum capacitor of 10uF in parallel with a ceramic capacitor of 0.1uF.
