2 z! Q: h" J% X" ^/ I8 ~ k0 u我的意思是,有什么标准能证明,证书:220-240V、50/60Hz,700-850W,铭牌不能随意配对的标示,比如230V,5 ... ; Z2 @4 c# l2 O5 e O7 t
看了标准IEC60335-1, 没看到哪里明确写出"铭牌不能随意配对": o h) j6 U! Q% m! y$ P
但是个人理解:
+ D7 b) p- ~3 L( _, Q9 t6 H7 k* L: m: S
1. 一个电压只会对应一个功率 (哪里有写则不知道 )如果铭牌能随意配对, 一个电压不只对应一个功率
2 m( A* ?7 r1 [3 O$ z
# o" A. L+ X4 S. T7 e& Q, n4 {* [# f$ {& H. Y) L
2. Clause 7.5写道2 X) N4 J+ _, ?0 G4 d3 E2 D
