Instruments and Illumination Training System China Engineering Lab Training System Suppliers
The multifunctional system integrates theory, practice, and examination, it is not only a trainer for electrical instruments and illumination, but also a skills examination system for maintenance electrician of different levels.
Mounting panel design for components facilitates operating and replacing components, and features expansion ability. In addition, typical and practical hands-on exercises can be performed
The system is 3-phase 4-wire AC voltage operated
Available voltage type and current type leakage protections ensure the human safety.
All devices and components have been brought out to terminals to avoid damage to the components caused by repeated exercises
The workbench allows two trainees operation simultaneously.
The workbench features two independent power supplies controlled by start/stop buttons and emergency stop button, short-circuit protection is available for the power output.
