1. The electric teaching aid adopts advanced design, and the experimental panel can be replaced freely. Students can replace it according to different training requirements. 2. The experimental instruments are digital display with high precision. The power and instruments used in this trainer are equipped with a reliable personal safety protection system.
1. Applicable to the teaching of "Basic Theory of Electrical Engineering" and "Electrical Technology". Thanks to its good expansion capabilities, the trainer can be extended to other training content such as "Programmable Logic Controller Technology" and "Motor Variable Frequency Control". 2. The front of the hanging test board is drawn with schematic diagrams and symbols, and the other side is welded with related parts. Components that need to be measured or observed use a locking connector. The experimental circuit adopts the unit circuit mode design. Each unit circuit is based on the basic circuit. By connecting different components or combining different circuits, students can practice various training contents on the trainer.
