引用第3楼a049405于2011-09-09 09:11发表的 :3 Q9 Y! i" H; f8 P4 y! L: e; F! M
IEC60598是有要求的  . S4 d8 a- E& H
謝謝4樓回復.
4 H( h5 m- z5 `0 E! R你指的是IEC 60598-1: 2008中Clause 5.2.2中的要求嗎:
1 t$ E* l* v1 ` k% S! ZNOTE For supply voltages greater than 250 V, higher voltage grade cables and cords than those given in the above table may be necessary.

/ e5 D) F) L" _& R- J, k; E在此處這個要求有指出是針對電源線的,而且還有考慮超過250V的情況,而明顯我手上的此產品是安全低電壓5V1A的,參照這個公用電網電源的標準來要求是否有意義?; M' Y! d% T! ?3 X' z7 z, D8 x
我一個5V1A或5V0.5A的重量30g左右微型的LED控制器,卻偏要配一條超過3倍重量的那麼粗的輸出線看起來會不會很滑稽?3 \9 R( W& j8 A6 s
