+ G7 y' c% n; _, k' B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:
" C% y/ t0 B. Z& F莱茵依据:
# o! E, x; o% ?2 h7 k22.26 Replacement:3 E6 B9 p M+ I7 g7 F! q6 `
The output circuit shall be supplied through a safety isolating transformer and shall not be/ s G& y2 R% [) Z

double insulation or reinforced insulation.

6 o% D2 T& E0 C d5 W& z然后参见 60335-1 safety isolating transformer 定义:

" B, @% k( u+ O* L
. n( C' V5 p" r, l. t7 C) G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,
@0 r8 Z) I" W3 V' {& q4 N* p/ p空载保护没有输出电压$ [. [( F% [2 _0 @+ X4 a
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/ C j) o7 J( T8 l' A5 l
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 f$ I" c5 n" y% e
