短路電流不能超過1.5倍的輸出電流?
客戶SPEC中有這么一句:“短路電流不能超過1.5倍的輸出電流.”據說是來自UL508,不知各位有無此資料,提供一份給在下.不勝感激!EMAIL:areast@sohu.com

i haven\'t seen it before!
but i think the short current should be slow as possible.assume the output current is 4A, according to your information, the short current should be at less 6A, it is so big that the circuit can\'t endure such large current.
Maybe the peak-peak short current will exceed 6A,
but the average short current should be much slower than the normal output current.
Or it can\'t say the circuit is in short operation.

it is rms value
the psu can operate in hiccup mode,and auto-recovery,the short current is RMS value.
