FAQ
1. Can this stabilizer support a commercial refrigerator?
Yes. The 20KVA model is suitable for large household refrigerators and most commercial refrigeration equipment.
2. Is the input voltage range customizable?
Yes. We can customize 45–260V, 100–260V, 140–260V, or any range based on your local grid.
3. How is this stabilizer different from relay-type AVRs?
Servo motor AVRs offer higher precision, smoother voltage correction, and better durability.
4. Does it protect against sudden voltage spikes?
Yes. It includes overvoltage, overload, and delay protection to prevent damage from power fluctuations.
5. Can I use this AVR for other appliances besides refrigerators?
Absolutely—air conditioners, TVs, pumps, and other home or commercial electronics.
