SF760 Series High-Performance Vector Frequency Inverter
SF760 Series High-Performance Vector Frequency Inverter
The basic function of a VSD is to control the flow of energy from the mains to the process. VSD sit between the electrical supply and the motor. Power from the electrical supply goes into a drive and the drive then regulates the power that is fed to the motor.
Power Range:
Three Phase AC 340V-460V 0.75kW-560kW
Three Phase AC 520V-690V 18.5kW-450kW
