1 Design original intention

The first problem facing electronic design enthusiasts is probably the power supply problem. Therefore, generally everyone has their own desire to design and weld a linear regulated power supply, but it is difficult to obtain satisfactory results due to the limitations of various conditions. The purpose of introducing this board is to make it convenient for people to use the regulated power supply with various power outputs and to save their own design and cloth.PCBBoard, manufacturePCBBoard trouble. It can be used for occasions requiring constant voltage power supply and constant current source.

2 Main input parameters

(1)220VAC power input.

(2) using double12VThe power of the transformer is determined according to the output power. Because of the convenient and flexible socket, the transformer can be replaced at will. (finished product transformer default 10W, due to purchase batch problem, illustration transformer picture for reference only)

3 Main output parameters

(1Linear DC regulated power supply.7Power output, respectively.+3.3V,+5V,-5V,+12V,-12VAdjustable voltage source and adjustable constant current source. Each power source has multiple output and is easy to use.

(2Unique design.All power outlets are provided with outlet holes to facilitate user multimeter interface.

(3The maximum output current of each power source is800mA.

(4The maximum ripple voltage of each power supply is less than that of the power supply.2.5mV.

(5The self recovery fuse is designed to provide 1A overcurrent protection..
