What Is a Servo Voltage Stabilizer?
A servo voltage stabilizer is an advanced type of automatic voltage regulator (AVR) that uses a servo motor to control voltage fluctuations in real-time. Unlike traditional relay stabilizers, it provides continuous, precise correction—ideal for sensitive equipment and environments where stable voltage is non-negotiable.

Key Benefits of SKW Series Servo Voltage Stabilizers
- Wide Input Range: Handles input voltages as low as 110V or 140V up to 260V, depending on configuration.
- High Precision Output: ±3% regulation ensures equipment safety and reliability.
- Smart Display: Digital interface shows input/output voltage, load status, and fault indicators.
Why Choose a Servo Stabilizer Over a Relay Stabilizer?
- Precision: Servo stabilizers offer real-time, fine-tuned regulation compared to the stepped correction of relay models.
- Reliability: Ideal for mission-critical equipment where voltage stability directly impacts performance.
- Longevity: With fewer abrupt switchings, servo models typically experience lower wear and tear.
- Smooth Output: No waveform distortion makes them safe for sensitive electronics.
If you’re powering computers, laser machinery, or diagnostic equipment, a servo model is your best bet.
Buying Guide – What to Consider Before You Purchase
When selecting a servo voltage stabilizer between 8KVA–15KVA, keep these in mind:
- Load Capacity: Check the total wattage of all connected devices. Add a safety margin of 20–30%.
- Voltage Conditions: Know your local voltage variation. If voltage often drops below 140V, opt for the 110–260V version.
- Space Requirements: While compact, the 15KVA version is taller—check your installation space.
- Application Type: For delicate devices like medical or lab equipment, always choose a servo model over a relay model.

FAQ
Q1: What is the price range for an 8–15KVA servo voltage stabilizer?
The price depends on input range, protection features, and customization. On average, 8KVA units start around $120–$180, while 15KVA models range from $240–$350. Contact us for an exact quote based on your configuration.
Q2: Can I use a servo stabilizer with inductive loads like motors or pumps?
Yes, but make sure the selected model has a capacity 2x to 3x higher than the equipment’s rated power to handle inrush current.
Q3: What kind of maintenance do these stabilizers require?
Servo stabilizers are generally low-maintenance. Keep the unit dust-free, ensure proper ventilation, and have the servo motor inspected annually for optimal performance.
