SKM20 Medium Voltage Inverter
SKM20 medium voltage inverter, featuring long-term stable operation, precise control, easy maintenance, high efficiency, simple operation and more advantages, effectively improves the running performance of industrial motors, pumps, fans and etc. By using SKM20, it can bring you a lot of benefits such as decreasing system maintenance cost, increasing productivity and more.
SKM20 VFD is designed with intuitive user interface that it is easy to set parameters, check fault records and more.
Low harmonic distortion
Because of using phase-shifting rectifier transformers, SKM20 do not bring obvious harmonic distortion to power grid.
Data processing and control accuracy
SKM20 medium voltage inverter adopts the latest components such as TI DSP F28335 and ALTERA FPGA, SKM20 stands out from our competitors’ products with powerful processing capability and high control accuracy.
SKM20 medium voltage inverter is designed with simplified control system reduces the number of external components and failure points.
Optical fiber communication and opto-isolator guarantees the full isolation between weak current and strong current what protects the system against interference.
SKM20 control system is composed of touch screen, programmable logic controller and mainboard serial structure, so it effectively reduces the data circulation, balances the data processing pressure of each module. As it adopts serial communication in data transmission, the anti-interference ability of the system has been greatly enhanced.
Safe to replace filter
SKM20 is designed with compact structure and professional layout. Its unique filter design allows replacing filter cotton safely during the running process.
Power factor compensation
Input power factor is higher than 0.97, with no need of power factor compensation equipment.
High working efficiency
The output current waveform is close to sine wave, harmonic distortion is less than 2%, output frequency is greater than 97.5%.
The fault diagnosis and protection function is complete so that the system can achieve long-term stable running.
Its control system is of dual-power supply what ensures the system do not lose power during the running status.
