Rolling Contact Type Servo Stabilizer

Servokon is a reliable supplier of high quality rolling contact type voltage controller that is used to overcome problems like electricity fluctuation. We understand the fact that even a minor fluctuation can not only halt the entire system but damages the electric appliance or devices as well. This type of controller protects the appliances by providing a constant output voltage when the voltage coming from the source of power fluctuates. We have an in-house manufacturing unit for manufacturing the voltage controller with utmost precision and at par with international standards. Highest degree of electrical insulation and windings makes these controllers suitable for both indoor as well as outdoor electric installations.
