FAQ

1. What is a digital display relay AVR?
A digital display relay AVR is a home voltage regulator that uses relay switching technology to stabilize voltage within a safe range. It displays real-time input/output voltage, load status and fault indicators, helping protect household appliances from power fluctuations.

2. Is relay AVR suitable for low-voltage countries?
Yes. The input range supports 45-260V / 80-260V / 100-260V / 140-260V, making it ideal for areas with severe voltage drop such as Africa, Southeast Asia, South America and the Middle East.

3.What happens when voltage is too high or low?
The AVR activates automatic protection based on built-in voltage thresholds:
Overvoltage ≥ 245V
Low voltage ≤ 180V
Undervoltage protection can also be customized.

4.Is relay AVR noisy?
Relay AVR has very low operating noise because there is no servo motor. It is suitable for bedrooms and indoor environments.
