The 15 amp AR-15II delivers a stable 120 volts of AC power to protect equipment from problems caused by AC line voltage irregularities such as sags, brownouts, or overvoltages - all of which can cause sensitive electronic equipment to malfunction or sustain damage. The AR-15II accepts any input voltage from 97V to 141V and transforms it to a constant 120V, ±5V. Voltages beyond that range may also be converted to usable levels, depending on the range variance. Furman's advanced technology allows us to offer superior performance in a one rack space unit at a cost effective price point.
