Servo Voltage Regulator

Servo Voltage Stabilizer uses an advance electronic controlled servo motor to govern a motorized variable transformer. Because of the motors involved, there is a small delay in voltage correction. However, output voltage accuracy is usually ±1% with input voltage changes in rage of 340 to 480 VAC. This type of technology tends to be extremely effective when considering large three phase applications, as it is able to maintain its accuracy of all these phases, despite of input voltages balance and load balance at any power factor.
