WEG CFW11 VSD

A variable speed drive, VSD, provides speed control of a three-phase induction motor in a wide variety of industrial applications. By providing precise control of the motor’s speed and torque a VSD improves efficiency and saves energy by meeting the process needs precisely.

WEG CFW11 VSD is state of the art vector control of motor speed, or torque, in closed loop or sensorless modes.
