Description of this 560KW to 630KW Economical inverter and low price frequency inverter from Powtech
The Economical inverter high power model has the following features:
1. Using IGBT power components to clamp direct series, direct speed control (DSC), anti-common mode voltage and sine wave output and other key technologies, the product has unique technical advantages and outstanding cost performance.
2. Direct high-high solution, no input, output transformer and external reactor or filter device; the system is simple and reliable, the operating efficiency of the full speed regulation section is not less than 98%, higher than other types of high voltage inverter products.
3. Unique anti-common mode voltage and sine wave output technology, the inverter output can be directly connected with ordinary high-voltage motor. There is no special requirement for motor insulation and output lead length, especially suitable for retrofit projects; output voltage waveform distortion is less than 3 %, approximate to a perfect sine wave.
4. The power frequency bypass system can be set in the device to ensure that the device can continue to operate in the event of a fault in the inverter.
5. The power unit adopts modular structure design, automatic diagnosis and recording of faults and faults; system maintenance and repair is simple and easy, which ensures efficient operation after the system is put into use.
6. Good man-machine interface, perfect protection function and communication interface.
