莱茵依据：, Z, V; [2 {; t4 p. i8 C

( M* V* k7 Q5 g% Z* q: t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，
" a, ^ _8 \& o- }空载保护没有输出电压
( m, w" _2 w5 H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
. ^6 L% i3 ]" o9 J9 A- i- Y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！！！！！9 W* T- p! }; L8 B! x
