The Netsavers Line Conditioner utilizing automatic voltage correction and conditioning, produces a clean, filtered, sinewave output, that is better for your computer system. A Sag, also known as a brownout, is a short term decrease in voltage level. A sag may last from a few milliseconds up to a few hundred milliseconds. Sags of longer than about 10 to 20 milliseconds may cause computer equipment to malfunction.
Electric companies use sags to cope with extraordinary power demands.
Sags also reduce the efficiency and life span of electrical equipment, particularly motors, and computer power supplies.
