What Is a Voltage Stabiliser?
A voltage stabiliser, also known as an electric stabiliser, is an essential power protection device that automatically regulates voltage levels to deliver a stable output to connected equipment. Whether your area suffers from low voltage, voltage fluctuations, or sudden surges, a stabiliser helps prevent damage to appliances by ensuring a consistent 240V output (or customized value as needed).

Key Advantages of DVB & SVB Voltage Stabilisers
Wide Input Range: Operates efficiently across various voltage ranges (45V–260V, 80V–260V, etc.) to suit regional power conditions.
High Accuracy: Output voltage regulation up to ±3% for servo models and ±10% for relay models.
Two Control Options:
DVB Series: Relay-type for cost-effective, stepped correction.
SVB Series: Servo-type for smooth, real-time voltage regulation.
Smart Protection System: Includes overvoltage, undervoltage, overtemperature, overload, and time-delay protection.
Digital Display: Real-time monitoring of input and output voltage.
High Efficiency: >95%, ensuring minimal energy loss.
Compact Design: Space-saving wall-mount and floor-standing options available.
How to Choose the Right Voltage Stabiliser?
Before purchasing, consider:
Load Capacity: Add up the wattage of all devices to be connected. Add 2–3X extra to select the appropriate VA rating.
Input Voltage Range: Know your area’s power fluctuations and choose the appropriate input range.
Control Type: Servo for high accuracy, relay for cost-efficiency.
Installation: All models can be wall-mounted or floor-standing depending on your space.

FAQ
Q1: Can I use these stabilisers with air conditioners or refrigerators?
Yes. Both DVB and SVB models are suitable for home appliances. For inductive loads like air conditioners, choose a model rated 30–50% above the appliance’s power rating.
Q2: What is the difference in precision between relay and servo stabilisers?
Relay models generally offer ±10% accuracy, while servo models provide ±3%, making them better for voltage-sensitive equipment.
Q3: Do these stabilisers require regular maintenance?
Not much. Just keep them clean and ensure proper ventilation. For servo models, occasional checks on the servo motor are recommended.
