Servo Voltage Stabilizer Manufacturers

Servo stabilizers are today’s popular stabilizer models used everywhere. COSMOSTAT is a well-noted servo stabilizer manufacturer and supplier in Delhi & NCR, India.

We offer the best oil-cooled servo voltage stabilizers for customized applications to diversified clientele across India and abroad.

Our products are made with efficient manufacturing, testing, and quality control standards. Also, we construct them carefully following the IS 9815 -1994 standards. So, they are reliable, trustful, and safe to use. We use oil with specific characteristics helpful for stabilizer function. The oil is made to circulate evenly throughout the unit by using the best capillary tube systems.

The three-phase oil-cooled servo stabilizers of COSMOSTAT assure trouble-free voltage regulation and thereby, play a wonderful role in power saving and management. With a customer-centric focus, we manufacture three-phase oil-cooled servo controlled voltage stabilizers with capacities ranging up to 1500kVA. Our products are preferably built with ultimate customization for indoor and outdoor applications.

Standardized servo motors are utilized to design these three-phase oil-cooled servo-controlled voltage stabilizers. The architecture of these units includes specific motors are intended to vibrate the oil in the fins. Our units are developed to withstand the capacity range up to 1500kVA. Apart from indoor usage, we also customize the units to suit for outdoor applications. -----
