An overview,

"Nakedness JXZK - 2 type automatic control principle of the comprehensive experimental platform is combined with the current development trend of electronic technology experiment, experiment box maintenance for aluminum alloy, easy to go bad, process the general characteristics, research and development of new electronic technology experiment box, can complete automatic control principle, the virtual instrument using now for the development of electronic technology, the modular design, the new design at the same time the regulated power supply, all digital design, greatly improves the reliability and efficiency.

Technology configuration

* 1. The experimental platform is designed with a full range of molds and has a beautiful appearance. It is made of high-quality PVC and black engineering plastics. Leave virtual oscilloscope, virtual signal source interface, power interface, I/O interface and other common interfaces. Each bin can hold four modules at once.

2. The module is made of 2mm thick printed circuit board, with the graphic symbols of components and corresponding wiring printed on the front and the printed circuit printed on the back, and the related components are welded. Easy maintenance. High quality galvanized pole can be used to complete circuit power supply. Provide common test units.

3. The experiment box shall be equipped with the voltage regulator required for the experiment. The voltage regulator shall be equipped with no less than ±5V/ 0.5a, ±12V/ 0.5a and the constant voltage regulation range of 0 ~ 18V/ 0.75a; Constant current current adjustment range 0 ~ 200mA/18V), all digital design, with communication interface and the whole network data monitoring function, can be upgraded to provide LABVIEW and mobile phone APP software and other cloud tools, with short circuit protection and automatic recovery.

4. Provide experimental instruction and other teaching resources. The wires have different colors.
