請問電路板背面變壓器一次側和二次側的距離
是遵守IEC60950標準還是IEC950標準啊?
還有UL1950好像也可以是嗎?
請問哪位好心人可以發一份標準給我啊?如果可以請注明哪一頁呀

好可憐,沒人理你.:)至于說要符合哪個標準,要看你的這個產品應用在什么方面,你說的標準都是舊版的了,最新的是IEC60950-1或UL60950-1你所說的距離要求,是需要具體測試之后才能確定的,大概的話8mm應該差不多了,標準在其它帖子里有呀.一份耕耘一份收獲喲.
個人覺得8MM也是足夠的
不過我拿五六個其他許多ADAPTER拆開了量一下
發現它們的距離竟然有4.5MM,5.6MM,5.4MM的都有哦
但是查以前的標準EN60950或者UL60950
其表格所給出的標準并不是這樣
首先,上面所說的ADAPTER的輸入是110-220交流市電,輸出分別有5-18V
如有高手可照著表格指點一二
即是輸入是110-220交流市電,輸出大約是12V時
可以參考表格中哪個距離?

the subclause 2.10 you referd is about IEC60950-1?
is that mean i can determined the distance according to IEC60950-1 2.10?
could you pleased give me a image to direct?
just like i have done before

the image you uploaded is one of the images in the subclause 2.10 of IEC60950-1,
yes,you can determine the distance according to the subclause 2.10 of IEC60950-1,but you should conduct the working voltage test at first.
the CL generally is between 4.0 and 5.0mm, the CR generally is between 5.0 and 8.0mm determined by the working voltage value, Vp and Vrms
