FAQ
Q: What is a wall-mounted automatic voltage stabilizer?
A: It is a small AVR device that can be mounted on a wall. It stabilizes fluctuating voltage to protect appliances from overvoltage, undervoltage, and surges.
Q: Why do I need a stabilizer?
A: Voltage fluctuations can damage electrical appliances. A stabilizer keeps the voltage stable, prevents overheating and failure, and helps appliances operate more efficiently.
Q: Which appliances can use this stabilizer?
A: It supports TVs, refrigerators, air conditioners, computers, printers, small equipment, and other low-power devices.
Q: How do I choose the right model?
A: Select based on total appliance power.
– About 400W → choose 1000VA
– About 1800W → choose 5000VA
Choosing a slightly larger capacity prevents overload.
Q: What are the installation requirements?
A: Mount on a solid wall with good ventilation. Avoid moisture and direct sunlight. Wiring should be done by a qualified electrician. The unit has a 6-second or 180-second delay start to protect connected equipment.
