An auto voltage stabilizer (AVR) is a device that automatically regulates fluctuating input voltage to deliver a stable output, protecting appliances from damage caused by surges, sags, or unstable power supply. Widely used in homes, industries, and commercial spaces, these stabilizers ensure consistent performance for sensitive equipment like refrigerators, AC units, and industrial machinery.
Types of Auto Voltage Stabilizers
- Single-Phase Automatic Voltage Stabilizer
- Designed for residential use, supporting 110V-240V systems (e.g., TVs, lights, small appliances).
- Three-Phase Automatic Voltage Stabilizer
- Handles heavy-duty industrial loads (380V-415V), ideal for factories, hospitals, and data centers.
Key Features & Benefits
- Automatic Voltage Regulation (AVR): Adjusts voltage in real-time without manual intervention.
- Surge Protection: Shields devices from voltage spikes.
- Energy Efficiency: Reduces power waste, lowering electricity bills.
- Wide Input Range: Works with voltages as low as 90V or as high as 300V.
Factors Affecting Automatic Voltage Stabilizer Price
- Capacity (kVA): Higher capacity = higher cost.
- Phase Type: Three-phase stabilizers cost more than single-phase.
- Brand & Manufacturer: Reputed automatic voltage stabilizer manufacturers (especially from China) offer competitive pricing for bulk orders.
- Features: Digital displays, time delays, or bypass switches add to the price.
FAQ
