Application
It is widely used in petrochemical, iron and steel smelting, mine coal yard, power plant, sewage treatment plant and other relatively harsh field environment, mainly driving high pressure water pump, fan, compressor, mill, conveyor belt and other equipment.
This equipment can be used in places with bad heavy load and service conditions according to the requirements of users. It provides a variety of starting curve selection to ensure that the starting current of the equipment is small, the starting speed is smooth, and the starting performance is stable and reliable, which has the advantages of less impact on the power grid and its mechanism equipment.

Technical advantages

1. Outstanding start and stop characteristics: torque control, current control and pump control.

2. Advanced motor protection.

3. Simple test run and maintenance-the site can be tested with a low-voltage motor.

4. 7 inch touch screen display, upload dynamic screen in real time.

5. Signal classification processing and isolation technology is used to make the system have strong anti-interference ability.

6. The advanced optical fiber transmission control technology is adopted to realize the safety isolation between the trigger of the         high voltage thyristor, the detection and the high and low voltage control loop.

7. Using High Frequency Power supply isolation and Transmission Technology to improve the trigger Reliability of Thyristor.

8. With PLC as the control core, the networking with the ground center and the remote control function can be realized.

9. Keyboard operation, design more humanized

10. Communication: MODBUS-RTU, MODBUS-TCP and other agreement
