The Unique servo control voltage stabilizers are extremely efficient stabilizers which meet the requirements of majority of your voltage fluctuation problems. Unique servo control voltage stabilizer are Electromechanical unites in which silicon solid state devices are employed to provide high reliability as well as long maintenance free service.
Unique servo control voltage stabilizers

Special advantages offered by Unique servo control voltage stabilizer include virtually no wave from distortion, wide frequency range, very low internal impedance and efficiency better than 90%. The rated accuracy of the out put voltage is + 1% for all variations of line voltage or load current within the limits specified. Servo control voltage stabilizer are insensitive to the magnitude and power factor of the load and do not affect the system power factor.
