Product Description

Main technical features

1. Integrated fast open door structure, modular design with small size, compact structure for easy installation, use and maintenance.

2. Independent heat transfer system by water and air, closed water cycle design, no need on-site water supply, adapt to all kinds of bad underground environment.

3. Excellent driving performance, wide speed regulation, high control accuracy, large torque with low frequency, with control mode of voltage frequency, open loop vector, closed loop vector.

4. High performance speed control, torque control, especially suitable for scraper conveyor, belt conveyor and other machine with requirements of low speed and large torque.

5. CAN communication between multi VFD, has high dynamic power equalization capability and can realize multi-machine synchronous operation.

6. Equipped with large-size intrinsically safe color touch screen, monitoring different data in real-time, direct touch screen operation, easy to use.

7. The output voltage waveform is close to sine wave, and the voltage change rate is small. It adopts 12 pulse wave rectifier and three level topology, which can effectively reduce the input and output harmonic content. Good electromagnetic compatibility which can meet the requirements of motor drive in long distance up to 3000m. It can reduce the insulation damage to the motor and prolong the service life of the motor.

Main application

Scraper conveyors

Belt conveyors

Other industrial area which constant speed regulation is required

Specification instruction

Note: A single water cooling device can satisfy the heat dissipation requirements of multiple VFD at the same time, and can simplify the on-site equipment configuration to reduce the site occupation which is especially suitable for important industrial place with redundant operation requirements of equipment and high reliability operation requirements.

According to the number of motor controlled in the user's field, the power supply unit and heat dissipation unit can be flexibly configured according to the actual use requirement in the field.
