Do you use AVR on your computer?

Short for Automatic Voltage Regulator, AVR is a hardware device used to maintain a specific voltage to electronic devices. do you use avr on computers or other devices? or connect your devices directly to the electrical plug or switches? Do you think its ok to use our computer or other devices without AVR?

We don't use AVR because there re now availble cheap UPS in the market and it's also regulate power. The main advantage is when there a power failure AVR turns off while cheap UPS can survive for 10mins long and you can save all your important documents and shutdown your computer properly.

yes your opinion is true, now UPS is gradually geting cheaper close to avr. so you can get a ups to replace your avr. but if you can, buy ups that allready included stabilisator, so you can get 2 advantage on one , 1. protect your system from sudden blackout, 2. protect your system from instable eletricity. thankx .

Normally we should use it since the voltage is not stable. There are special plugs for computers sold in market. These plugs can provide stable voltage for computers. Sometimes we even use a special power supply which provides stable voltage or current output in lab. If you study circuit in engineering areas, you will touch these devices.

lets define avr? automatic voltage regulators, this device keeps the power supply of your computer in a constant value, this device serves as a buffer and a control during power surges, for example a lightning storm is happening some miles away from your location and the electrical surges from the lightning produces spikes in the power that runs into your homes. without avr, this surges and spikes will toast your pc,literally, trust me, i had mine toasted during a thunder storm... avr works by reducing this spikes and grounding the excess power. and if its too much surge, its your avr that gets toasted and not your pc. UPS, is uninteruptable power supply, means it protects your pc during power shortage, low voltages and during power flickers, its like a back up battery. it works by switching power from your supply to its battery and back again if necessary, and most of UPS now a days have AVR in them...
