What is AVR and its function?

An automatic voltage regulator (AVR) is an electronic device that maintains a constant voltage level to electrical equipment on the same load. The AVR regulates voltage variations to deliver constant, reliable power supply.

How do I choose the right AVR?

CHOOSING THE RIGHT AVR Multiply the total wattage of the appliance/s by three (3). Result will be the basis of which AVR to choose. When using the 110V socket, the total computed wattage of the appliance/s plugged in the AVR should not exceed 50\% of the capacity of the AVR.

What is AVR regulation?

Automatic Voltage Regulation (AVR) in line interactive UPS systems stabilizes the incoming AC signal to maintain output power at a nominal 120 volts by controlling high and low voltages without resorting to battery power.

Why do we need AVR?

An AVR is usually necessary for appliances and equipments with electronic devices inside that may be sensitive to electrical surges. Simple home appliances that do not contain sensitive electronic devices like electric fans, blowers, portable radios, etc. do not need AVR’s.

Does a PC Need AVR?

If you live in an area with unreliable electricity, it would probably be a good idea to have an AVR or UPS. If you live in, say, the United States or Europe, an AVR is not necessary (though a UPS is still good to have; blackouts can occasionally happen anywhere).

Is AVR needed for inverter refrigerator?

AVRs should be used for refrigerators that have sensitive electronics. This includes inverter models, and those that have features like Door-in-Door and water dispensers. For non-inverter refrigerators, freezers, and beverage coolers, you can get away with not having an AVR.

Is AVR needed for TV?

Example appliances that require an AVR would include: Computer systems, refrigerators, Aircon, Flat screen TV, Audio/Video equipment.

Do you need AVR for treadmill?

AVR’s are pretty useless unless you have a VERY cheap power supply. Most treadmill power supplies are like PC or even laptop power supplies and support full range, meaning you don’t need an AVR unless your power drops all the way down to100V.

What is shunt voltage regulator?

The shunt regulator or shunt voltage regulator is a form of voltage regulator where the regulating element shunts the current to ground. The shunt regulator operates by maintaining a constant voltage across its terminals and it takes up the surplus current to maintain the voltage across the load.
