SERVO VOLTAGE STABILIZER
We provide end-to-end SITC (Supply, Installation, Testing & Commissioning) services for a wide range of Servo Voltage Stabilizers, including Dimmer-Based, Balanced Load, Unbalanced Load, and Linear Type models. Designed for Single Phase and Three Phase applications, these stabilizers are available in Air-Cooled and Oil-Cooled variants, with capacities from 5 kVA to 5000 kVA. Our voltage stabilizers ensure ±1% or better output accuracy, protect against over/under voltage, and reduce downtime across industrial, medical, commercial, and residential sectors.
With over 20 years of field experience, certified components, in-house technical teams, and full compliance with IS standards, we deliver tailored solutions with unmatched quality and post-installation support. Whether your site needs high-speed correction for sensitive equipment or rugged voltage control for heavy-duty loads, we offer custom-built stabilizers that ensure power reliability, energy efficiency, and long-term protection.
SITC of Servo Voltage Stabilizers
(Dimmer Type | Balanced / Unbalanced / Linear | 5 kVA to 5000 kVA)
We offer complete SITC (Supply, Installation, Testing & Commissioning) of high-performance Servo Voltage Stabilizers, including Dimmer-Based, Balanced Load, Unbalanced Load, and Linear Type models. Available in both Single Phase and Three Phase, Air-Cooled and Oil-Cooled, with capacities ranging from 5 kVA to 5000 kVA, our stabilizers are engineered to deliver precise voltage control, maximum energy efficiency, and equipment safety in fluctuating power conditions.
Backed by 20+ years of experience, we provide custom-built and fully tested solutions tailored to your exact load profile and site conditions.
Types of Servo Voltage Stabilizers We Offer
Dimmer-Based Stabilizers: Heavy-duty carbon brush dimmer-driven stabilizers, ideal for industrial and commercial applications.
Balanced Type (Three Phase – Common Control): Suitable where loads across all phases are almost equal.
Unbalanced Type (Three Phase – Individual Phase Control): Ideal for setups with varying or unpredictable load across phases.
Linear Type Servo Stabilizers: Use linear-type regulators for no waveform distortion and high-speed correction—suitable for medical, telecom, and precision industries.
Where Are These Used?
Servo Stabilizers are commonly used in:
CNC machines, elevators, plastic molding machinery
Hospitals, imaging & diagnostic centers
Commercial complexes, banks, data centers
Residential bungalows and villas with sensitive loads
Telecom towers, server rooms, laboratories
Key Benefits
