does anyone know this ? AVR ?

BudgetBoy · July 20, 2017

automatic voltage regulator ? its widely use in philippines for safety in there pc . i know ups is better but they use it as alternative for ups . (practically they dont care about data loss)

they said as long as they have avr there pc is safe ? does anyone explain to me what is an avr ?

here is the pic and the known brand

a AVR regulates the voltage supply, so lets say your voltage supply changes between 250 and 320V the AVR will change that to 240V and keep it constant at that no matter what the supply changes to, most UPS can also do this as well as having a battery back up for sometime to shut the system down if there's a power cut

i know ups can give u sometime to save and shut up without data loss . but the avr dont have this option . but is it still safe ?

as I said the AVR protects against over voltage as it supply's a nice even power supply to the PC, while a good UPS will do both that and give you a battery back up. So the AVR will protect you from over voltages from the mains supply, but if the power turns off your PC will turn off immediately making you lose work, so yes and no, it is better than nothing, especially if your voltage supply varies a lot in your country, but if you have anything important which you can't afford to lose then no, you need a UPS as it gives you time to try and save it that way
