A single phase voltage stabilizer, also known as a single phase voltage regulator, is an automatic electrical device that maintains a stable output voltage for single-phase power systems, even when the input voltage fluctuates beyond acceptable limits.
It continuously monitors the incoming voltage and automatically adjusts it to a safe, predefined level, helping prevent equipment malfunction, performance degradation, or permanent damage caused by unstable power supply.
How it works:
Detects input voltage fluctuations
Adjusts voltage using regulation technology
Delivers stable output to connected loads
✔ Suitable for both resistive and inductive loads
✔ Designed for continuous operation in industrial environments
Different applications require different regulation technologies. We provide the following single phase voltage stabilizer types to match performance, cost, and response requirements.
| Type | Regulation Accuracy | Response Time | Typical Applications |
|---|---|---|---|
| Servo Voltage Stabilizer | ±3% | Slow (mechanical) | CNC machines, medical equipment, testing instruments |
| Relay Voltage Stabilizer | ±10% | Medium | Office equipment, household loads, small commercial systems |
| Static Voltage Stabilizer | ±1% | Instant | Precision electronics, telecom, critical industrial loads |
Choosing the right single phase voltage stabilizer depends on more than just kVA rating. Below are the key parameters buyers should confirm before ordering.
Load power (kVA)
Input voltage range (e.g. 140–260V, 120–280V)
Required output accuracy
Load type (motor, resistive, mixed load)
Installation method (wall-mounted / floor-standing)
Engineering tip:
For motor or inductive loads, we recommend selecting a stabilizer with 20–30% capacity margin to handle starting current.
Our single phase voltage regulators are widely used across industries where voltage stability is critical to performance and safety.
Medical and laboratory equipment
CNC machines and automation systems
Printing and packaging machines
Telecom and IT infrastructure
Testing instruments and control panels

Yes. In most markets, the terms single phase voltage stabilizer and single phase voltage regulator are used interchangeably. Both refer to devices that stabilize output voltage despite input fluctuations.
The required kVA depends on your equipment’s rated power and load type. Motor loads usually require additional capacity due to high starting current.
Voltage stabilizers regulate long-term voltage fluctuations. For surge and lightning protection, external surge protection devices are recommended.
Most single phase stabilizers are designed for easy installation. Wiring diagrams and manuals are provided with each unit.
