Product Introduction
1. The experimental circuit is designed in the way of unit circuit. The unit circuit is the basic experimental circuit, and then other components are added as the parameters of the circuit, or combined with other unit circuits to complete different experimental requirements.
2. The experimental schematic diagram is printed on the surface of the panel, and the experimental circuit is built by students according to the experimental schematic diagram.
3. The experiment connection jack adopts the overlapping self-locking gold-plated jack, which is fixed on the experimental board by welding.
4. Discrete component zone, can plug resistors, capacitors, diodes, transistors, integrated circuits, etc., can carry out course design experiments.
5. The output of the power supply has over current protection and automatic recovery function.
