[backcolor=#ffffff]维修和DIY的必备家当 适合DIY自制(为了适合热转印采用[/backcolor][backcolor=#ffffff]单面板布线[/backcolor][backcolor=#ffffff]）稍微改变一下阻容参数即可改成 0-60V 0-10A[/backcolor]
[backcolor=#ffffff]0-30V 0-5A可调直流稳压电源 [/backcolor][backcolor=#ffffff]注意：[/backcolor][backcolor=#ffffff]采用TL431电压基准 + C5200大功率三级管 （处理好散热[/backcolor][backcolor=#ffffff]）[/backcolor][backcolor=#ffffff]          R10 R11 5W0.25R[/backcolor][backcolor=#ffffff]欧电流取样  C1 C2大电容选63v2200 -10000uf均可 U1 7812 U2 7912 [/backcolor][backcolor=#ffffff] 稳压[/backcolor][backcolor=#ffffff]          IV 4.7K电位器 （电流调节）PV 47K[/backcolor][backcolor=#ffffff]电位器（电压调节）IC LM358如需要可换TL082等芯片提高稳定精度[/backcolor][backcolor=#ffffff]          变压器 次级12v 24v经一两档开关输入到8A整流桥堆再连接到 C1C2 [/backcolor]
[backcolor=#ffffff]U3 431最好采用WS431 或TL431（手机、电动车充电器中大把拆）C5200 可用C5144 J6920代换其它无特殊要求！[/backcolor]
