Product Application

Products can be used in mining, fans, pumps, new energy equipment and other occasions.

Field irrigation

In agricultural irrigation, VFD for constant pressure water supply is almost standard. First of all, in the process of starting the pump, the VFD can gradually increase its operating frequency, so that the pump can run slowly, so that the water does not cause too much impact on the pipeline. The VFD can then be used in conjunction with a remote pressure gauge or pressure sensor to equalize the pressure in our pipes. Finally, the VFD can control the pressure protection pipeline, but also through its own overload, underload, overpressure, underpressure protection to reduce the damage of the pump.

FANS

The application of frequency converter in the field of fans not only greatly reduces energy consumption, but also improves the system accuracy and automation level through intelligent control. WCE's SCK300 series, with its high compatibility and energy saving algorithms, can cover the diverse needs of small ventilators to large industrial fans, helping companies achieve green and efficient production.

VFD volume is large structure, larger radiator, product utilization rate, can work normally in hot environment such as tropical.

Various types of input and output modes can be customized:

1.3P 380V input to 3P 380V output.

2. 3P220V input to 3P220V output.

3. 3P660V input to 3P660V output.

4. 1P220V input to 3P 380V output.

5. 1P220V input to 3P220V output.

With speed tracking function, can better double start.

It comes with MODBUS RTU communication, and can also implement MODBUS TCP, PRPFIBUS and PROFINET by adding expansion cards.
