补充楼上:标准里面的100mA,200mA是对于设备的要求,并非判断测试结果的判据。* i$ [% n/ M. j X
在60065里10.3.2有规定* O5 E% H2 P+ S# v6 }5 X0 s
The test voltages shall be obtained from a suitable source so designed that, when the output TERMINALS are5 ]! l3 @7 d% g. o$ @+ }

An over-current device shall not trip when the output current is less than 100 mA.

当输出电流小于100mA时,过流装置不应该打开。
