The importance of the usage of oil cooled servo voltage stabilizer having sensitive electronics as well as electrical equipment is well known to everyone. No one wants to take the risk the life of costlier appliances like CNC machine, electrical or electronics equipment, motor lab equipment, medical equipment, etc. by connecting AC voltage. The AC voltage as we know that the voltage is not stabilized one and dips at one point of time and rises at another point of time.

The output voltage of the oil cooled voltage stabilizer allows the optimum level of current by load and like this, there is no extra electrical power is required at low voltage and also for high voltage. That’s why Oil Cooled Servo Voltage Stabilizer manufacturer manufacture world-class oil cooled servo voltage stabilizer which helps in saving the power and reduces MDI. The microprocessor used in the oil cooled voltage stabilizer helps to operate in a flawless manner.  We are also becoming one of the leading Oil Cooled Servo Stabilizer suppliers in Hyderabad.  And because of the providing excellent quality stabilizers, Servomax is now considered as the best servo voltage stabilizer manufacturer in Hyderabad


The 3 Phase Oil Cooled Servo Controlled Voltage Stabilizers manufacturers manufacture the IC based solid-state, relay less oil cooled servo voltage stabilizer which controls for easy online serviceability. From the front panel, the output voltage of the stabilizer adjustable to ± 6% of the set voltage. The meters present on the front panel of the oil cooled voltage stabilizer for easy monitoring of input as well as output voltage along with limiting indicators. From the front panel, it has provision for Auto/manual control.  It operates between -20°C to 50°C. Because of the new innovations & improvements in the technical specifications, the servo voltage stabilizer manufacturer Servo Max manufactures the excellent quality oil cooled servo voltage stabilizer, air cooled voltage stabilizer, single phase voltage stabilizer and static voltage stabilizer.
