你不理会那只多出来的东东就是了

。。。就当它不存在。

我拿到的板子好象有个地方不同....(注意红笔的地方)

我收到的...(是不是我的本身就是修正了的板子?)

本坛子的！找钳子买！

用IC。。。还是要面对同一个问题

以下是引用HQ在2004-12-16 1:33:00的发言：
还是IC好!


除非有专门的丢电设计。。。UPC1237就没有，呵呵



文招 发表于 2004-12-16 11:27

其实

TA7317也颇好用的

丹麦王子 发表于 2004-12-16 07:51

。。。。。。。。。

拍照的水平怎么那么差劲？？？？1237在大电容后

丹麦王子 发表于 2004-12-16 07:49

我这个就是用1237，哈哈

大约5秒吸合

那也得看荷包啊

特别是商业应用

47U的是电源滤波吧？装全分立的保护电路时，用得太小继电器难吸合，用得太大关机又不能即时断开，有冲击声

呵呵

我刚刚才仔细看这个贴!

晕,小鬼头兄的是没加47UF电容的版本!这个版本根本没有对外!是当时设计PCB的时候开的第一版

对外的版本全部加了下面图中的47UF---大家放心使用,一切正常
