灯具III 结构的要求
各位同学!灯具III 结构除了以下要求外,还有别的要求吗?谢谢!:handshake
c) Class III luminaires may have exposed current carrying parts in the SELV circuit 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 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.
– the no-load voltage does not exceed 35 V peak or 60 V ripple-free d.c.
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 does not exceed 12 V
r.m.s. or 30 V ripple-free d.c.
你说的这个只是SELV裸露的要求。 楼主,这个是哪个标准里面的啊? 一条一条肠子,一句都看不懂:lol 这讲的是啥条件下SELV部件能裸露
