Types of Stabilisers
Voltage stabilisers come in different technologies, each designed to handle power fluctuations in a specific way. Knowing the types will help you pick the right one for your appliances.
1. Relay Type Stabiliser
Relay stabilisers use electromechanical relays to regulate voltage. When the supply exceeds or falls below the safe range, the relay switches to maintain the output.
- Best for: TVs, refrigerators, small home appliances
- Pros: Affordable, simple design, widely available
- Cons: Slight delay in correction, less precise than servo models
2. Servo Controlled Stabiliser
Servo stabilisers use a servo motor and a variable transformer for smooth and precise voltage correction. They respond quickly and maintain a very stable output.
- Best for: ACs, medical equipment, expensive electronics, and offices
- Pros: High accuracy (±1% voltage control), handles wide fluctuations, long life
- Cons: More expensive and slightly heavier
3. Static / Digital Stabiliser
Static or digital stabilisers use microcontroller-based circuits (no moving parts) to correct voltage electronically.
- Best for: Sensitive electronics, home theatres, smart TVs, gaming consoles
- Pros: Silent operation, fast correction, energy-efficient, compact size
- Cons: Higher cost compared to basic relay stabilisers
4. Mainline Stabiliser
Mainline stabilisers are installed at the entry point of the home’s electrical supply. They protect all connected appliances together.
- Best for: Entire households in areas with severe voltage fluctuation
- Pros: Whole-house protection, one-time installation
- Cons: Expensive upfront, needs professional installation
How to Pick the Best Stabiliser for You?
Voltage Range & Load Capacity: Different appliances need different levels of power. Pick a stabiliser that supports the voltage swings in your area (e.g., 90–300V) and can handle your appliance’s wattage with 20–30% extra capacity for safety.
Thermal & Surge Protection: Good stabilisers include thermal overload protection to shut off power if the unit overheats. Look for overload and surge protection to prevent damage from overheating or sudden power spikes.
Display & Indicators: Digital or LED displays show input/output voltage and alerts if there’s a problem, so you know the stabiliser is working. This helps you instantly know if your power supply is safe.
Energy Efficiency: Energy-efficient models lower your electricity bills and reduce heat generation, making them better for long-term use.
Warranty & Service: A long warranty (3–5 years) and a wide service network mean hassle-free repairs or replacements.
User Reviews & Reputation: Choose brands with strong reviews and reliable after-sales support for long-term peace of mind.
