' M; J1 f2 |9 i$ r- t1 X, w莱茵依据：

" l) A: _; g8 n9 H6 R5 Y
* R3 I9 S9 ]5 r7 K. q! l- j) X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，4 q6 `7 P6 Y& T6 g7 x9 s
空载保护没有输出电压1 j @, }# V4 @; }
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
# M. D: h( n1 N8 d# J; W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！！！！！
