莱茵依据：" w) J' C. K0 r# q# b0 q& x
22.26 Replacement: `( r" \7 p) E8 u- {3 e2 j% S

$ f: m3 x6 i& y N, G( |: N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，
+ j2 r& D" |" v( d6 Z- F* O空载保护没有输出电压$ c" }( e0 E8 {1 R8 K! o+ r2 O8 s
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
! w% V, I. x1 X1 i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！！！！！. d$ O7 H' o/ p+ Z0 a, v
