数控直流稳压电源源程序 本设计由两个电路模块构成：直流稳压源电路（+15V,+5V,-15V），程控电路。并且巧妙得反置使用D/A变换器。使程控输出电压0-9.9手动可调，步距为0.2V。并可预置电压值，采用LED同步显示。-NC DC power source circuit of the design of two modules: the source DC circuit (+15 V,+5 V,-15V), program-controlled circuit. And clever use of a reversal of D/A converter. So that the output voltage programmed manually adjustable 0-9.9, step to 0.2V. And preset voltage value, shows that the use of LED synchronization.
