AET Servo-Motor Automatic Voltage Stabilizer







AET Servo-Motor Automatic Voltage Stabilizer provides a continuous monitoring of the output voltage true RMS by
means of an Electronic Control Circuit that compares the instantaneous output voltage with the set value. When
changes are detected due to fluctuation of supply voltage or sudden change in load, an electrical signal will be
transmitted to the servo-motor which is coupled onto the brush gear of the variable transformer, which causes the
brush gear to rotate until the appropriate voltage is restored. This method of stabilization does not create
interference nor harmonics in the supply system.
AET Three phase Automatic Voltage Stabilizers are also designed to cater for unbalanced load. This is made
possible with its independent phase monitoring system.
