Industrial & Commercial Voltage Stabilizers
Protect your valuable equipment from power fluctuations. ServoKai System manufactures heavy-duty voltage stabilizers for homes, offices, and large-scale factories.
Ultimate Protection Against Voltage Fluctuations
Unstable power is the leading cause of electronic failure in India. A sudden spike can cause irreversible damage, while a voltage drop forces motors to work harder, generating excess heat and ultimately burning out.
ServoKai voltage stabilizers are engineered to absorb these shocks. From compact 1 KVA units for domestic appliances to massive 2000 KVA industrial installations, we provide complete power conditioning solutions.
- Prevents equipment burnout from high voltage
- Stops motor overheating during low voltage
- Reduces electricity bills by improving efficiency
- Increases the lifespan of connected machinery

Frequently Asked Questions
What is a Voltage Stabilizer?
A voltage stabilizer is an electrical appliance that maintains a constant voltage supply to a load. It automatically corrects under-voltage and over-voltage conditions in the power supply, protecting sensitive appliances and industrial machinery from electrical damage.
Why do I need a Voltage Stabilizer in India?
The power grid in many parts of India is prone to severe voltage fluctuations. High voltage can instantly burn out equipment, while low voltage forces motors to draw more current, leading to overheating and reduced lifespan. A stabilizer acts as a protective shield.
What is the difference between Automatic and Servo Stabilizers?
Automatic (Relay-type) stabilizers use electronic relays to switch transformer taps, correcting voltage in steps (e.g., ±9% accuracy). Servo stabilizers use a motor-driven variac for stepless correction, providing highly precise output (±1% accuracy) essential for sensitive equipment.
How do I choose the right KVA rating?
Calculate the total wattage of all devices connected to the stabilizer. Add a 20-30% safety margin. Convert watts to KVA (Watts / 1000 = kW; assuming power factor 0.8, KVA = kW / 0.8). If you are unsure, our engineers can help you calculate the exact requirement.
