【正文】 and production figures show that the DC power supply. The power supply as a ministarter with adjustable voltage regulator range , and output voltage can be displayed with the function. This article describes the display section and the output DC ponent. Power supply regulator part of the integrated threeterminal regulator with a LM317 pleted, the digital display section plete with TCL7107 chip. TCL7107 is a very broad application on the market integrated chip, builtin program, you can directly drive LED digital tube. The design of the display part of the chip is produced using TCL7107 LED display digital voltmeter, in parallel to the output voltage display function to plete.
