Voltage Stabilizer Price Guide: From 2kW to 30kVA
Looking for a voltage stabilizer but confused by the different prices and types? Whether you are choosing a 10kVA servo voltage stabilizer, a 5kVA automatic voltage stabilizer, or a 2kW home voltage stabilizer, this guide will help you understand its cost, features, and how to choose the right one.
What factors affect the price of a voltage stabilizer?
The price of a voltage stabilizer depends on the following factors:
Capacity (kVA or kW): The higher the capacity, the higher the cost.
Technology: Servo stabilizer, static stabilizer, or relay stabilizer.
Number of phases: Single or three phase.
Protection features: Overload, surge, and short circuit protection.
Brand, manufacturing quality, and compliance (CE, ISO9001, etc.).
Common voltage regulator prices by capacity
| Capacity | Type | Approx. Price (USD) |
|---|---|---|
| 2kW | Relay Type Stabilizer | $30 – $60 |
| 3kVA | Automatic Voltage Stabilizer | $50 – $90 |
| 5kVA | Servo Voltage Stabilizer | $100 – $160 |
| 6kVA | Relay/Servo Stabilizer | $120 – $180 |
| 10kVA | Servo Voltage Stabilizer | $180 – $260 |
| 10kVA | Automatic Voltage Stabilizer | $150 – $240 |
| 30kVA | Servo Voltage Stabilizer | $450 – $650 |
Note: Prices vary based on input voltage range (e.g. 140–260V vs 100–280V), copper content, and display/control interface.
Servo, Relay, Static IGBT: What's the Difference?
All three are automatic voltage regulators, but the internal mechanisms are different:
Servo voltage regulator: Uses servo motor + carbon brushes to precisely regulate voltage. Suitable for CNC machine tools, medical equipment and motors.
Relay regulator: Switches voltage via relays; cheap, but less accurate. Best for home appliances such as TVs, refrigerators and lighting, small industrial equipment and commercial locations.
Static regulator: Uses power electronics such as IGBTs and has no moving parts. Has a fast response, ideal for places with high voltage requirements such as computers or laboratories.
Cost-effectiveness recommendations
Home use:
Use a 2kW–5kVA automatic relay regulator, which is economical.
Office/store:
Use a 6kVA–10kVA servo regulator, which has a wide input range.
Factory:
Use a 10kVA–30kVA servo regulator, which has copper windings and digital control.

FAQ
1. What is the difference between 10kVA and 10kW regulators?
kVA is apparent power; kW is real power. For resistive loads, 10kVA ≈ 10kW. For inductive loads, check the power factor (usually 0.8), so 10kVA ≈ 8kW.
2. Which regulator is best: relay regulator, servo regulator or static regulator?
Relay regulator: Good for low-cost home use.
Servo regulator: Best for medium to heavy applications.
Static regulator: Great for sensitive and responsive loads.
3. How to choose the right voltage stabilizer?
Calculate your total load in kVA or kW
Add 20-30% safety margin
Choose the type (servo, relay, static) based on the accuracy required
Make sure the voltage input range matches your grid conditions
