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。
& d" y5 I8 n# l; c# `在60065里10.3.2有规定
" y0 y* q5 c9 n7 z. Z, x( ]The test voltages shall be obtained from a suitable source so designed that, when the output TERMINALS are7 s" ]) q+ w; Q

least 200 mA.

试验电压应该由合适的电源提供,该电源的设计应保证当试验电压调节到相应的等级后,短路输出端子时,输出电流至少为200 mA.

所以一般来说,如果是65的规章,耐压测试机不能直接接到市电上, 必需用隔离变压器的source提供power. |
