請(qǐng)問(wèn)電路板背面變壓器一次側(cè)和二次側(cè)的距離
是遵守IEC60950標(biāo)準(zhǔn)還是IEC950標(biāo)準(zhǔn)啊?
還有UL1950好像也可以是嗎?
請(qǐng)問(wèn)哪位好心人可以發(fā)一份標(biāo)準(zhǔn)給我啊?如果可以請(qǐng)注明哪一頁(yè)呀

好可憐,沒(méi)人理你.:)至于說(shuō)要符合哪個(gè)標(biāo)準(zhǔn),要看你的這個(gè)產(chǎn)品應(yīng)用在什么方面,你說(shuō)的標(biāo)準(zhǔn)都是舊版的了,最新的是IEC60950-1或UL60950-1你所說(shuō)的距離要求,是需要具體測(cè)試之后才能確定的,大概的話8mm應(yīng)該差不多了,標(biāo)準(zhǔn)在其它帖子里有呀.一份耕耘一份收獲喲.
個(gè)人覺(jué)得8MM也是足夠的
不過(guò)我拿五六個(gè)其他許多ADAPTER拆開了量一下
發(fā)現(xiàn)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(biāo)準(zhǔn)EN60950或者UL60950
其表格所給出的標(biāo)準(zhǔn)并不是這樣
首先,上面所說(shuō)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(diǎn)一二
即是輸入是110-220交流市電,輸出大約是12V時(shí)
可以參考表格中哪個(gè)距離?

ThelatestversionareIEC60950-1,EN60950-1andUL60950-1.Theinsulationdistanceneedstomeasureworkingvoltagetodetermineclearanceandcreepage.Youcanrefertosubclause2.10.
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
