Open source SMU precision power supply equipment

The SMU is a precision power supply device that can measure not only high-resolution voltage sources but also high-resolution current sources. It also integrates bipolar voltage and four-quadrant output functions to facilitate testing of various characteristics. By providing a linear sweep voltage and sweep current, the IV characteristic curve of the instrument can be obtained.

Diansai source code three-phase electronic multi-function energy meter

It is mainly composed of the basic functions and structure of the professional electric energy measurement chip ATT7022B and the single-chip computer MSP430F149 system. In terms of hardware circuits, the electromagnetic compatibility of the circuit is fully considered in the circuit design. A more reliable power supply for electric energy meters is designed to improve the ability to withstand lightning strikes. And it is proposed to use EPROM to store data in order to achieve the purpose of simplicity and security. In the particularly critical communication unit of the electronic energy meter, multiple communication methods such as serial communication and wireless communication are designed to connect scattered electricity meters into a network to achieve centralized control and remote meter reading functions. In addition, a GPS module is designed to locate the coordinates of the collection point.
