Why Choose Voltapex

Engineering Advantages That Matter

  • 01

    Precision Servo Motor Control

    Our stabilizers use high-torque servo motors with carbon brush or brushless design for lightning-fast response — correcting voltage deviations in under 10 milliseconds.

  • 02

    Wide Input Voltage Range

    Handles extreme grid fluctuations — from as low as 50V to as high as 300V input — ensuring uninterrupted, stable output of 220V / 415V ± 1%.

  • 03

    100% Copper Wound Transformers

    We use only electrolytic-grade copper in all our windings — never aluminum — guaranteeing lower losses, longer life, and better thermal performance.

  • 04

    Microprocessor-Based Control

    Advanced digital control panels with LED/LCD display, over/under voltage protection, time delay, and remote monitoring capability as optional feature.

Frequently Asked Questions

Everything About Servo Stabilizers

What is a servo voltage stabilizer?

A servo voltage stabilizer is an automatic voltage regulator that uses a servo motor to control the position of an auto-transformer, delivering a precise, stable output voltage regardless of input fluctuations — typically maintaining ±1% regulation.

How is a servo stabilizer different from a relay-based stabilizer?

Servo stabilizers offer step-less, continuous voltage correction with ±1% accuracy — far superior to relay-based models that switch in fixed steps of ±2% to ±6%. Servo types are essential for sensitive equipment.

Which capacity servo stabilizer do I need?

Add up all connected loads in watts, divide by 1000 to get KW, then factor in power factor (typically 0.8 for motors) to get KVA. We recommend adding a 25% safety margin. Our engineers can help you size correctly.

Do you supply servo stabilizers in Delhi NCR?

Yes, Voltapex Power is based in Delhi and serves the entire NCR region including Noida, Gurgaon, Faridabad, and Ghaziabad, with fast delivery and on-site installation support.

What is the warranty on Voltapex servo stabilizers?

All Voltapex servo stabilizers come with a standard 24-month manufacturer's warranty covering defects in materials and workmanship. Extended warranty and AMC contracts are also available.

Can you manufacture custom KVA ratings?

Absolutely. We manufacture custom servo stabilizers from 1 KVA to 500 KVA in single-phase, three-phase, and special configurations as per client specifications and site requirements.
