100KVA Servo Voltage Stabilizer - AltraVolt Power

Industrial Giant

Overview

The AltraVolt Power 100KVA Servo Voltage Stabilizer is the pinnacle of our single‑phase voltage regulation range, delivering massive power handling capability for the most demanding industrial and commercial applications. With a power rating of 100 KVA, it is engineered to protect large‑scale manufacturing plants, data centres, medical imaging facilities, and critical infrastructure from voltage fluctuations that can cause catastrophic downtime and equipment damage.

This model features a monumental, heavy‑duty construction with reinforced anchor points, triple high‑capacity cooling fans with intelligent thermal management, and an advanced servo‑motor driven variac that maintains a stable output of 230V ± 1% even when the input voltage swings between 160V and 280V. Its high efficiency (≥98%) and comprehensive protection suite, including overload, short‑circuit, and surge protection, make it the ultimate choice for environments where reliability and uptime are absolutely critical.

How It Works

⚙️ Servo Motor Control

A servo motor continuously adjusts a variable autotransformer (variac) to maintain the output voltage at the desired set point. The control circuit monitors the output voltage and compares it with a reference; any deviation triggers the motor to rotate the variac in the appropriate direction, correcting the voltage instantly and smoothly. This stepless correction ensures that there is no hunting or relay switching noise, providing uninterrupted clean power.

📈 Feedback Loop

A precision feedback loop ensures that the correction is accurate and fast. With a response time of less than 40 milliseconds, the stabilizer can handle sudden voltage surges or drops without interrupting the load. This closed‑loop system guarantees a stable output even under fluctuating grid conditions, protecting your equipment from stress and premature failure.

Installation & Maintenance

🛠️ Installation Guidelines

Place the stabilizer in a well‑ventilated area, away from direct sunlight and moisture.
Ensure the input and output wiring are correctly sized as per the current rating.
Connect the earth ground properly to ensure safety.
Allow at least 30 cm clearance on all sides for airflow.
For heavy models, ensure the floor can support the weight and use the anchor bolts if required.

🔧 Routine Maintenance

Visually inspect for dust accumulation every 6 months.
Clean the ventilation grilles and fans with a soft brush or vacuum.
Check all electrical connections for tightness.
Test the protection features (over/under voltage cut‑off) periodically.
Inspect fan operation and replace if noisy or failing.

Frequently Asked Questions

What is the difference between a servo stabilizer and a relay stabilizer?

A servo stabilizer uses a motor‑driven variac for stepless voltage correction, providing precise output (within ±1%) and fast response. Relay stabilizers use step‑changes via transformers, resulting in slower correction and larger output tolerances (±5‑10%).

Can this stabilizer be used for three‑phase equipment?

The 100KVA model is single‑phase. However, we offer three‑phase servo stabilizers up to 500KVA. Please contact us for your specific three‑phase requirements.

Is the stabilizer suitable for sensitive medical equipment?

Yes. With its high precision, low noise, and optional isolation transformer, it is ideal for medical imaging, diagnostic devices, and laboratory instruments.

What is the typical lifespan of this stabilizer?

With proper maintenance, the servo stabilizer can last over 15 years. The brushless servo motor and robust components ensure long‑term reliability.

Do you provide installation support?

Yes, we offer on‑site installation and commissioning services across India. Our engineers will ensure the system is set up correctly for your application.
