Servo Controlled Voltage Stabilizer 3 Phase Oil Cooled

Servo Controlled Voltage Stabilizer

Servo Controlled Voltage Stabilizer 3 Phase Oil Cooled

June 2, 2018   0 Comments

The main function of the Servo Voltage Stabilizers is to provide a stabled voltage output to the input of the various electric applications for the safe working of the respective appliances.




It is categorized into two types, Oil Cooled Servo Voltage Stabilizer, and Air Cooled Voltage Stabilizer. We are also known as the Best Oil Cooled Servo Voltage Stabilizer Manufacturers in Bangalore offering the high quality and wide range of products.

Thus, three phase oil cooled servo stabilizer is designed with the latest technology support and solid-state electronic circuitry to control a wide range of voltage fluctuations. As it is an Oil Cooled Servo Voltage Stabilizer, it acts as an automatic line voltage corrector with the help of servo motor to provide a constant voltage output. Thus, the natural oil cooled up to 500kVA is used as a type of cooling in Oil Cooled Servo Voltage Stabilizer. We have rich industry experience and are well-known Oil Cooled Servo Voltage Stabilizer Manufacturers in India.

We have designed the Three Phase Servo Stabilizer Oil Cooled offering the low voltage and high voltage protection circuitry to deliver the prescribed output voltage. Along with the various components, MCB is also used in Three Phase Stabilizer for the protection of short circuit and overloading. Therefore, we offer the Best and High-quality Oil Cooled Voltage Stabilizer at Best Price in India.

For supplying power to the appliances, which are not at ground potential, an isolation transformer is needed. Among the transformer manufacturers in Bangalore, our isolation transformers are more prone to the safety of the appliances, without which touching a circuit can be very dangerous and can cause severe damage. As one of the leading isolation transformer manufacturers in Bangalore, we are very cautious about the overall safety of the transformer and do every testing of the transformer.
