CLASS Ⅱ插头是双插

CLASS 0Ⅰ插头虽是双插但要附接地线

如果电源模块是class II 电源，这可以用UL1310 来测试认证。class II 电源是指采用隔离型变压器，输出电压低于直流60伏， 电流小于150/Vmax安培的电源。 而对非class II电源， 则采用UL1012来测试认证。

class 2和classⅡ是不同的概念。

class 2电源最基本的要隔离变压器和功率不大于100W

楼上正解，UL1310里面也有具体的定义

kellysun

是不是输出高于60V 时就不能过UL1310了，如果输出高于60V如何过1012呢

faige2006

class II是双重绝缘。
