Comprehensive Electrical Engineering Experiment Euipment 5556SA55 Vocational Training Equipment

I. Basic Functions:
1. The Comprehensive Electrical Engineering Experiment Platform can support experimental teaching in a variety of university courses, including circuit analysis, electrical engineering, circuit principles, and electronic technology.
2. The accompanying measuring instruments are highly accurate, digital, intelligent, and feature human-computer interaction. All instruments have reliable protection functions.
3. The operating panel of the Comprehensive Electrical Engineering Experiment Platform utilizes a 2mm thick aluminum panel. The text and symbols are processed using modern color inkjet printing technology, ensuring clear panel markings. The aluminum panel color matches the color of the lab bench.
4. The Comprehensive Electrical Engineering Experiment Platform utilizes a modular structure, with power supplies and instrumentation all housed in independent hanging boxes. Each experimental module has a clearly defined function, allowing schools to customize their experimental configurations based on their own teaching requirements and facilitating future expansion and upgrades. The working power supply between experimental modules is connected by shorting wires, which not only connects the power to each module but also ensures a seamless connection between them. 5. The comprehensive electrical engineering experiment platform is equipped with a voltage-type leakage protection device. If leakage occurs, it generates an alarm signal and cuts off the main power supply, ensuring safe experimental progress. A current-type leakage protection device is also installed. If leakage occurs, it will cut off the power supply when the leakage current exceeds a certain value. All power supplies and instruments have reliable protection functions. Experimental connection cables and sockets use different structures, ensuring safe, reliable use, and preventing electric shock.
