2.3 Max. Input AC Current Max. Input Current Measuring Range 12A 90 - 264 Vrms 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.

Time Diagram Figure 1 Power Supply Timing * T1 : Turn on time ( 500mS Max.) * T2 : Rise time ( ≦ 20mS Max.) * T3 : Power good turn on delay time ( 100 < T3 < 500 mS ) * T4 : Switch on time (10mS Max.) * T5 : Power hold-on time ( 16 mS Min at 70%load) * T6 : Power good turn off delay time ( 1.0 mS Min.) * Power on-off cycle : When the power supply is turned off for a minimum of 2.0 sec. and turn on again, the power good signal will be asserted. 10. MTBF The MTBF of the power should be 100,000 hours min.
