Equipped with voltage-type leakage protector and current-type leakage protector to ensure the safety of the operator; each power output has functions such as monitoring and short-circuit protection, when misoperation occurs during training or short-circuit due to wiring errors , The device can automatically protect to avoid burning the fuse and damaging the electrical appliances, ensuring the smooth progress of the training;

7. The control screen is also equipped with a timer and alarm recorder (service manager), which provides a unified standard for the assessment of students' experimental skills;

8. The connection between the training circuit and the power supply of the device is through the safety socket and the high-reliability sheath structure pistol plug-in wiring, which is safe and fast;

9. The device is equipped with a three-phase power output short-circuit soft cut-off protection function, which prevents short-circuit damage to components due to incorrect wiring or misoperation during the training. At the same time, it can ensure the smooth progress of the training and save the cost of training.
