FAQ
What Is AVR Automatic Voltage Regulator
An Automatic Voltage Regulator (AVR) is an automatic regulator that stabilizes the output voltage. It can automatically regulate input voltage fluctuations so that electrical appliances or equipment are provided with stable power supply and are not damaged by high or low voltage. It detects input voltage fluctuations and adjusts the output voltage automatically with the assistance of relays to change transformer taps, servo motors for driving voltage regulators, thyristors (SCRs) or PWM technology to adjust the output voltage to the desired range for the safe operation of the device.
How to choose a suitable AVR?
When choosing an AVR, you should consider the following:
● Input voltage range – choose a model which can withstand the range of variation of the power grid.
● Load power – ensure that the AVR rated power is 20-30% higher than the equipment power.
● Regulation accuracy – For precision equipment, it is recommended to choose a servo motor or electronic AVR.
● Response time – For the equipment that puts high requirements on voltage variations, SCR or PWM type AVR can be selected.
● Protection function – Make sure that the AVR has protection functions such as overvoltage, undervoltage, overload, etc.
Is the AVR applicable to generators?
Yes, but you have to choose a generator dedicated AVR because normal AVRs may not be able to withstand the frequency and voltage fluctuations of the generator.
