In this paper, the design of a NC DC regulated power supply, the power supply is composed of MCU circuit, display circuit, analog / conversion circuit, amplifying circuit composed of four parts. The singlechip circuit is used for controlling the voltage of the input signal, digital / analog conversion circuit for converting a digital signal to analog signals, a display circuit for displaying the output voltage. At the same time, this paper analyzes the concept of digital technology and simulation technology of mutual conversion. Compared with the traditional regulated power supply regulated power supply, the design has the advantages of convenient operation, using the high stability of powerand the output voltage digital display characteristics. Digital positive negative adjustable dual DC regulated power supply module is put forward aiming at the shortage of traditional intelligent power module, digital will reduce the uncertain factor sand human participation number in the production process, effectively solve the problems such as reliability, intelligent and product consistency and other engineering power module,which greatly improve the production efficiency and the product maintainabi
