Product Name: 
440vac, 460vac high performance energy conservation vector control frequency changer(frequency converter, AC drive, VSD)
Model:  PI8000 440 VAC vector control frequency changer   
Product Details:

440vac, 460vac, 480vac world class high performance energy conservation vector control frequency changer(frequency converter, AC drive, VSD)

Application area:
1.Mine working machines: Belt Conveyor, scraper conveyor, Coal feeder machinery, pump, fan, etc.

2.Oilfield Machinery: Oilfield Machinery, Electrical submersible pump, etc.

World class high performance energy efficient vector control frequency changer(frequency inverter, AC drive, VSD) , high performance, first rate quality and low noise.

This sensorless vector control frequency changer (VSD) achieves quick response and precise control by decoupling control of motor magnetic flux current and torque current, which makes the speed adjustment and torque control run at a high degree of accuracy and wide range. 

Our first rate vector controlled frequency changer (frequency converter) has the advantages of high efficiency, low noise and low electromagnetic interference.
