What is a Servo Controlled Voltage Stabilizer?
 These are simply termed as servo stabilizers (work on servomechanism which 

also known as negative feedback) and the name suggests it uses a servo motor to 

enable the voltage correction. 
 These are mainly used for high output voltage accuracy, typically ±1 percent with 

input voltage changes up to ± 50 percent. 
 These stabilizers can be: 

•  Single-phase, 

•  Three-phase balanced type or three-phase unbalanced units.
