51單片機(jī)0-30v 4A數(shù)控電源

ID:138783 · 發(fā)表于 2016-9-7 22:55

給51黑論壇的朋友們分享一個(gè)不錯(cuò)的51單片機(jī)0-30v 4A數(shù)控電源.就是成本有點(diǎn)高！兩路輸出：1：0-30V/4A 2: 5V/1.5A（固定輸出）

電壓分辨率0.458mV，電流分辨率0.076mA
電壓步進(jìn)0.0073V，實(shí)際用的是0.1V步進(jìn)調(diào)節(jié)

在制作中發(fā)現(xiàn)；C37極性畫(huà)反了！還有就是復(fù)位電路是51和AVR都兼容的，不能把四個(gè)原件都焊接上去，
用什么芯片就焊接什么樣的復(fù)位電路！特此告知！
