System configuration

The training device mainly consists of a training platform, a power cabinet, a training circuit board, a component package, and a tool kit. The training device has a two-sided, two-group structure, with the same resources on both sides.

Training platform

This system is designed for 4 stations on both sides. Two fluorescent lamps (for lighting) are provided on the training platform. Four transparent PVC boards can be used to hold schematics and other information. In addition, it is also equipped with four three-core dual-socket sockets There are two two-core concealed sockets and two tool cabinets. The work surface is equipped with a green anti-static table mat, and the entire assembly line is safe and reliable. Size: 1.5M × 1.3M × 2M (double-sided type)
