We are a world class manufacturer and exporter of Power Conditioning Solutions providing the best quality products and services to our customers.

Rolling Contact / Linear Type Servo Voltage Stabilizers detects the unexpected voltage fluctuations of the power supply and reduce or increase the voltage levels with the help of Servo Motors (an important component of servo stabilizers), and then provide a stabilized, high output voltage to the end devices.

To ensure better cooling of the Servo Voltage Stabilizers, Transformer Oil as per IS:335 is used. Oil cooled Servo Voltage Stabilizers are the best solution for industry to avoid voltage fluctuation.

High Efficiency and Precise Voltage Regulation

With over 98% efficiency and a regulation accuracy of 1%, this stabilizer is designed to deliver consistent and reliable voltage to sensitive equipment. Negligible waveform distortion ensures uninterrupted, quality power, protecting devices from voltage fluctuations.


Versatile Design and Rugged Construction

The stabilizer is adaptable for both indoor and outdoor installations with enclosure protection ratings of IP21, IP22, or IP54. Designed as floor-mounted units, they can be customized in dimensions and terminal connections to suit varied environments and load requirements.


User-Centric Operation and Advanced Control

A user-friendly digital display for voltage and current readings enhances monitoring. The microprocessor-based control system provides fast corrections at 35V/sec, while under/over voltage protection and overload capacity (120% for 5 minutes) ensure operational safety.

FAQs of Rolling Contact Linear Type Servo Voltage Stabilizer Upto 5000 KVA:


Q: How does the stabilizer maintain consistent output voltage despite input fluctuations?

A: The microprocessor-based control system adjusts voltage rapidlyat a correction speed of 35V/sec. It maintains the output voltage at either 400V 1% (three-phase) or 230V 1% (single-phase), compensating for input variations between 340-480V (three-phase) or 170-270V (single-phase).

Q: What are the cooling options and when should each be selected?

A: Depending on installation requirements and environment, you may choose between air-cooled or oil-cooled models. Air-cooled is ideal for moderate conditions, while oil-cooled variants suit higher capacity installations or environments with elevated ambient temperatures.

Q: Where can this voltage stabilizer be installed?

A: This stabilizer is suitable for indoor or outdoor installation, based on specific site requirements. The enclosure protection can be customized to IP21, IP22, or IP54, ensuring reliable operation across industrial, commercial, medical, or institutional settings.

Q: What benefits does this stabilizer offer for sensitive electronic equipment?

A: Precise voltage regulation, negligible waveform distortion, and microprocessor-based controls protect sensitive electronics from voltage surges and fluctuations. This minimizes downtime and potential damage, ensuring operational reliability and longevity of connected equipment.

Q: How does the stabilizer handle overloading?

A: It is engineered to operate at up to 120% overload for five minutes, allowing it to manage temporary surges in demand without compromising performance or safety. Built-in voltage protection features further enhance equipment safety.

Q: What compliance and standards does this product meet?

A: The stabilizer conforms to IS 9815 and IEC 60076 standards, ensuring it meets international benchmarks for safety, efficiency, and performance in varied operational environments.
