Rolling Contact / Linear Type Servo Voltage Stabilizer

Rolling Contact / Linear Type Servo Voltage Stabilizers detects the unexpected voltage fluctuations of the power supply and reduce or increase the voltage levels with the help of Servo Motors (an important component of servo stabilizers), and then provide a stabilized, high output voltage to the end devices.

To ensure better cooling of the Servo Voltage Stabilizers, Transformer Oil as per IS:335 is used. Oil cooled Servo Voltage Stabilizers are the best solution for industry to avoid voltage fluctuation.
