怎么讲呀？什么意思？
如果定义为带电部件了，就不可以触摸了的吧。
那刚标准那条是出于什么情况来考虑的呀？25V
有没有专家级的人来回答下啊，感觉同样的产品，不同机构的报告，这条判断都不一样。
顶一下，没人回答
没看过GB的, IEC 61347-1 以及 IEC 60598-1 都是满足下面2个条件一个就OK：
1. 25Vac or 60Vdc
2. 不满足1的条件就touch current 有要求.
最新版的598 还分了IP20灯具跟非IP20灯具,
非IP20 12AC or 30VDC
10.4 Controlgears providing SELV may have accessible conductive parts in the SELV circuit;
if: the rated output voltage under load does not exceed 25 V r.m.s. or 60 V d.c. ripple free d.c.
where the voltage exceeds 25 V r.m.s. or 60 V ripple free d.c., the touch current does not
exceed:
–for a.c.: 0,7 mA (peak);
–for d.c.: 2,0 mA;
–the no-load output does not exceed 35 V peak or 60 V ripple free d.c.
c) SELV circuits may have exposed current carrying parts under the following conditions.
–For ordinary luminaires:,
•the voltage under load does not exceed 25 V r.m.s. or 60 V ripple-free d.c. and
•the no-load voltage does not exceed 35 V peak or 60 V ripple-free d.c.
where the voltage exceeds 25 V r.m.s. or 60 V d.c., the touch current does not exceed:
•for a.c.: 0,7 mA (peak);
•for d.c.: 2,0 mA.
If the voltages or currents exceed the values given above, at least one of the conductive
parts in the SELV circuit shall be insulated by insulation capable of withstanding a test
voltage of 500 V r.m.s. for 1 min.
–For luminaires which are other than ordinary the nominal voltage (under load and under
no load) does not exceed 12 V r.m.s. or 30 V ripple-free d.c.. When the luminaire is
opened for light source replacement, the voltage limits for ordinary luminaires are
applicable (for parts only accessible during maintenance)
大哥，你这是灯具的，我是说控制器的。
不管输出多少V，SELV或者非SELV都可以直接用引线输出

大哥，你这个问题放错版了吧？

版主，如图，额定输出电压超过25V的控制装置应装有绝缘接线端子，这个是出于什么考虑的？如果是安全特低电压 ...
哪本标准？哪章哪节？
