Servo controlled air cooled servo voltage stabilizer is a stabilizer which continuously monitors the output voltage and helps to control the input voltage variations with the help of 3 phase motor. Automatically it can regulate the voltage. A stabilizer is really very important for a stabilized performance of any electronics or electrical equipment that regulates as well as maintains the input voltage. A fluctuation, whether high or low, it can be harmful to the voltage sensitive devices.

Hence our air cooled servo voltage stabilizer manufacturers manufacture the air cooled servo voltage stabilizer to stabilize the frequent fluctuations and considered as one of the leading servo stabilizer manufacturers in Hyderabad

The air cooled servo voltage stabilizer consists of three single-phase units, which are connected in star. Each unit of the air cooled servo voltage stabilizer has a motorized single phase variac and a series transformer.


To protect the electronics or electrical appliances, this is the perfect solution. Servomax, one of the top 3 Phase Air Cooled Stabilizers manufacturers offers air cooled servo voltage stabilizer to customers, which has very high demand in the market. Not only its air cooled voltage stabilizer, but also its oil cooled servo voltage stabilizer, single phase voltage stabilizer, Linear Automatic Voltage Stabilizer  and static voltage stabilizer carry a quality value.  

The air cooled servo voltage stabilizer is generally observed AC main supply, which is never perfectly 230 volt or 415 volt and varies between 150 volt to 300 volt and 300 volt to 500 volt.  The voltage fluctuation, low energy production can be overcome by an air cooled servo voltage stabilizer. The under voltage decreases the efficiency and also shortens the life span. And only the best quality of air cooled servo voltage stabilizer can control the voltage. Another advantage is, there are several losses like overload condition, low power factor, line losses, which are certain things which are caused by the stabilizers. But our air cooled servo voltage stabilizer is well capable to reduce these losses in an efficient manner. We give a guarantee that the voltage will be under the safety limits.
