Servo Voltage Stabilizers detect 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, natural air or transformer oil (IS:335) is used. Oil cooled Servo Voltage Stabilizers and Air-cooled Servo Voltage Stabilizers are the best solution for industry to avoid voltage fluctuation.

Advanced Voltage Regulation TechnologyOur three-phase Servo Voltage Stabilizers employ advanced automatic servo motor control to maintain output voltage at 400 V 1%, even with input fluctuations from 340480 V. These stabilizers are designed for industrial settings, featuring high efficiency, negligible waveform distortion, and a fast response time of less than 30 milliseconds, ensuring optimal equipment performance and protection.
Durable Construction for Rugged EnvironmentsBuilt within robust steel enclosures (IP21/IP23), our floor-mounted stabilizers withstand challenging industrial conditions. Cooling is facilitated either by oil (natural/forced) or air, as per the model, allowing continuous operation at ambient temperatures between 045C and up to 95% relative humidity (non-condensing). Transformer winding options (copper or aluminum) cater to diverse operational needs.
Comprehensive Safety and User FeaturesSafety is prioritized with automatic under/over voltage protection and an optional automatic bypass. Digital LED or analog meters offer clear operational data. The systems low noise level (<60 dB at 1m) and high insulation resistance (>5 Megohms) reduce disturbance and enhance long-term reliability, contributing to safer and more efficient industrial power management.
FAQs of Servo Voltage Stabilizers Three Phase Upto 5000 KVA:
Q: How does the servo voltage stabilizer maintain consistent output voltage for industrial equipment?
A: The stabilizer uses an automatic servo motor control system, which continuously monitors and corrects output voltage at a rate of up to 35 V/sec, ensuring the output remains at 400 V 1% despite fluctuations in the input supply (340480 V). This safeguards sensitive industrial equipment from voltage disturbances.
Q: What cooling methods are available for these stabilizers and how do I choose?
A: Models are available with either oil-cooled (natural or forced) or air-cooled systems. The choice depends on your installation environment; oil cooling is ideal for higher capacities or warmer settings, while air cooling suits moderate loads and ambient temperatures. Our team can advise the best option for your needs.
Q: When should automatic bypass be considered in the stabilizer setup?
A: Automatic bypass is recommended for facilities that cannot afford any downtime, as it allows continued power flow even during stabilizer maintenance or failure. It is optional and can be included based on criticality and reliability requirements of your application.
Q: Where are these servo voltage stabilizers typically installed?
A: Primarily designed for industrial and large commercial settings, these floor-mounted stabilizers are placed near main power supply entries, switchgears, or dedicated electrical rooms to ensure efficient stabilization of the entire facilitys power supply.
Q: What is the process for maintenance and monitoring?
A: Routine inspection involves checking enclosure integrity, cooling system operation, and cleaning dust filters. The digital LED or analog meters display real-time operational parameters, aiding in quick monitoring. Regular servicing by qualified technicians is recommended for optimal lifespan.
Q: How does using a servo voltage stabilizer benefit industrial operations?
A: Servo stabilizers enhance equipment life by protecting against voltage fluctuations, reduce downtime, and contribute to energy efficiency with their 98% operational efficiency. The negligible waveform distortion (<1%) ensures sensitive devices remain unharmed.
