大家好！



美规1598标准中对电击危险定义与8750的定义略有区别，8750里的电压限值为30 V rms or 42.4 V AC，60 V DC。





1598对电击危险的定义：



Risk of electric shock – in Canada and the United States, a risk of electric shock exists between any two uninsulated conductive parts of a luminaire or between an uninsulated conductive luminaire part and earth ground if the continuous current flow through a 1500 resistor in parallel with a 0.15μF capacitor connected between the two points exceeds 5 mA rms (7 mA peak) and if the open circuit voltage exceeds 30 V rms or 42.4 V peak for dry, damp, and wet locations.

在上面条款中，电压限值为30 V rms or 42.4 V。那直流输出的限值是否被认为是42.4V？而UL 1993标准中的此定义和UL 1598标准中的定义很相像，相关的差异为“than 30 Vrms, 42.4 Vpeak (and DC) ”。

请问，在使用有class 2输出认证的电源时，如果直流电压超过42.4 V，那么用于1598适用的灯具时，电源输出端子是否被视为危险带电部件？

谢谢！
