Servo Controlled Voltage Stabilizer



Servo Controlled Voltage Stabilizer save the life of costly appllances, cnc machines, electrical equipment, medical equipment, motors lab equlpmen by correcting the voltage fluctuations in the incoming AC voltage and bringing and keeping in at the desired voltage levels. It involves comparing the output voltage with built-in stable reference voltage source. The control circuit operates the motor whenever the output voltage falls or rises beyond the preset voltage. The control circuit controls the servo motor. The motor is mechanically attached to the arm of a continuously variable auto transformer which feeds to the primary of a series control buck boost transformer. The stabillizer output voltage is compared with the reference voltage & resultant error signal controls the servo motor which corrects the voltage by bringing it to the preset voltage.

Description :

  • GEESYS Servo Voltage Stabilizer Corrects Voltage Fluctuations before it damages your Hi-tech Machines.
  • The purpose of GEESYS Servo voltage stabilizer is to receive a fluctuating AC voltage of low or high amplitude & deliver an almost constant voltage, at the output. The voltage variations, which have become a common phenomenon in power supply systems, cause havoc in modern advanced electronic equipments. The voltage stabilizers are meant to take care of this problem. They avoid breakdown, ensure longer life of the equipments & save in energy during high incoming voltages.
