" D! i( b/ ~. I" u6 D; s6 S各位好,现在有一款 电池充电器做GS 现在不讨论其他机构的看法,因为就莱茵有以下要求:2 U0 D: _* h# P2 X" W
莱茵依据:

( G) h' P' o2 w4 E9 P+ Z' m现在抛出问题 ;我的充电器输出端子插入电池座是不可触摸的,输出是 29.4V 2A,正常异常测试输出都小于42.4V,
( c/ p* }3 u O6 J5 y空载保护没有输出电压
+ y% W) I( ^' A/ D但莱茵按照 safety isolating transformer的定义 一定要求我变压器输出端要小于42V,才能做60335-2-29的GS,我个人
U6 F& Y% _4 N觉得很没道理,这个地方的safety isolating transformer 不能这么理解,还请各位发表下看法,以便我能找到更好的依据,多谢!!!!!
