A. AVR stands for automatic voltage regulation. A unit equipped with AVR is able to take sagging or high voltage and correct them into an acceptable range without using battery power. Units that are not equipped with AVR will still protect the load in the event of a power sag or spike, but they will simply switch to battery which may drain the battery and cause the UPS to turn off the load once the battery is depleted. All Matrix-UPS units and most Smart-UPS units are equipped with AVR.
