因为模拟电路的IC对多路电源是要求同时通电的，如果用多个电源单元会存在电源通电时间有差异的问题，可能会损坏昂贵的A/D转换IC或D/A转换IC，不同时通电的电源也会对运放产生冲击！）

感应加热等功率大的东东那么可以买一个通讯开关电源改成可调这种改完的纹波很大噪声也很大所以可以买一个小电流的线性电源用作一般实验而推东西的话就用那个通讯电源哈爱玩高压的选通讯电源的话不要选择编程的切记因为一不小心被高压打报了的话可是得自己修的不是编程很好修一般开关电源从输出反馈开始查先看光耦那玩意隔离电压5000v如果坏了那么就差调压的那个运放限流的那个运放不容易坏因为人家是采采样电阻上面的电压滴和脉宽调制还有如果玩高频或者要求电源比较高的那么电源直接买成品吧不要贪便宜自制什么
