What Is Automatic Voltage Regulator?
Automatic voltage regulation(AVR) provides clean and stable AC power by automatically increasing low voltages during brownouts and decreasing overvoltages when irregularities are present on the main utility line.
Complete AVR protection against voltage irregularities is essential in areas where voltage fluctuations occur frequently, providing clean and stable power to loads.
Working Principle Of AC Voltage Regulator
How do AC voltage stabilizers work?
● Detect input voltage:
The AC voltage stabilizer first detects the actual value of the input voltage through the internal sensor.
● Compare and judge:
Compare the detected input voltage with the preset standard voltage to judge the voltage deviation.
● Adjustment mechanism start:
According to the voltage deviation, start the internal adjustment mechanism.
● Output stable voltage:
After the adjusted voltage is filtered and stabilized, a stable voltage value is finally output.
Electronic Voltage Regulator Application
optimized for residential and home office applications
Voltage Stabilizer placement environment:
→ Well ventilated.
→ Keep out of reach of children.
→ Safe and without risk of falling.
→ Keep away from any flammable substances.
→ Do not expose to direct sunlight or heat sources.
How To Choose The Appropriate Automatic Voltage Regulator
√ Determine Your Power Requirements
Power Rating (VA or kVA): Calculate the total power consumption of the equipment you want to protect. Add up the wattage of all connected devices and convert it to volt-amperes (VA) or kilovolt-amperes (kVA). It is recommended to select an AVR with a power rating 20-30% higher than your total power requirements to accommodate any future increases or unexpected surges.
√ Load Type:
Consider whether the load is inductive (motors, transformers), resistive (heaters, lights), or electronic (computers, sensitive electronics). Inductive loads typically require a more powerful AVR because they have higher starting currents.
√ Understand Voltage Fluctuations in Your Area
Input Voltage Range: Determine the typical voltage fluctuation range in your area. Select an AVR that can handle the minimum and maximum voltage levels you are likely to encounter.
Output Voltage Stability: Make sure the AVR provides a stable output voltage within a specified tolerance, typically ±1% to ±5%.
√ Physical and Environmental Considerations
Size and Weight: Make sure the AVR fits in the designated space and is not too heavy if you need to move it occasionally.
Operating conditions: Consider the temperature and humidity range in which the AVR will operate. Some AVRs are designed to work in harsh conditions.
√ Budget
Cost vs. Features: Balance your budget with the features and specifications you need. While it may be tempting to choose the cheapest option, investing in a high-quality AVR can save you money by preventing damage to your equipment.
Summary:
Choosing the right AVR is essential to protecting your equipment from voltage fluctuations and ensuring it has a long life and reliable operation.
