Dimmer Type Servo Voltage Stabilizers
Range- 5 kVA – 1000 kVA
Reliable & Efficient Voltage Regulation for Industrial and Commercial Needs

At RRR Spower Pvt. Ltd., the dedicated manufacturing arm of the esteemed RRR
Electricals in Noida, Uttar Pradesh, we specialize in the design and production of highperformance Dimmer Type Servo Voltage Stabilizers. Ranging from 5 kVA to 1000 kVA,
these robust units are engineered to deliver precise and stable output voltage, effectively
protecting your critical machinery and sensitive equipment from the detrimental effects of
mains voltage fluctuations.

In today’s electrically sensitive world, an inconsistent power supply can lead to significant operational disruptions, equipment damage, and reduced lifespan of valuable assets. Our Dimmer Type Servo Voltage Stabilizers are a proven solution, operating on an advanced servomotor-controlled variable auto-transformer (often referred to as a “dimmer” in this context due to its variable output). This mechanism continuously senses input voltage changes and automatically adjusts the output to maintain a constant, desired voltage level. This ensures a smooth, continuous, and highly accurate voltage correction, making them indispensable for applications demanding unwavering power quality.
Manufactured in our state-of-the-art facility, every RRR Spower Dimmer Type Servo Voltage Stabilizer undergoes a stringent multi-stage quality control process. From the selection of high-grade copper windings and robust mechanical components to the meticulous assembly and precise calibration, each step is optimized for perfection. All units are subjected to rigorous testing to ensure full compliance with national (IS) and international (IEC) quality and safety standards, guaranteeing optimal performance, high efficiency, and an extended operational life. Our deep engineering expertise, inherited from RRR Electricals, is embedded in every unit, ensuring reliability and durability.
