High Performance Three Phase AC Drive

WCE's SCK300 series is a high performance, versatile frequency converter designed for industrial automation, widely used in fans, pumps, conveyor belts, crushers and other equipment. Its core adopts advanced vector control technology, and has the characteristics of high precision speed regulation, energy saving, high efficiency and stable operation to meet the needs of diverse industrial scenarios. In addition, the SCK300 can be upgraded to the SCK350 by upgrading the control board, after which expansion cards can be added and applied to equipment such as cranes.

Product Application

Products can be used in metallurgy and chemical industry, compressors, cranes, municipal engineering occasions.

Crusher, sort stones of different sizes.

VFD is widely used in the crusher industry, it can be used in the impact crusher, jaw crusher, cone crusher, hammer crusher, etc. Can be used in high-power host, reduce the starting current, adjust the speed of the crusher, when the speed is reduced, but also can save about 50%. The frequency converter used in the crusher can reduce the mechanical impact and extend the service life of the equipment.

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.

Two display modes are available:

1.LCD display: Come with Chinese and English display, you can also customize Russian, Portuguese, Spanish, Persian and other languages.

2.LED display: traditional digital tube display, double line display, observe two sets of data at the same time.

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.
