The 15 amp AR-1215 AC Line Voltage Regulator is intended to protect audio, video, computer and other electronic equipment from problems caused by AC line voltage irregularities-sags, brownouts, or overvoltages that can cause sensitive digital equipment to malfunction, or, in extreme cases, to sustain damage.

The AR-1215 is designed to provide a steady, stable 120 VAC output. It 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 how far out of range they are. The AR-1215 can handle loads totaling up to 15 amps as long as the input voltage is above 124 volts. For voltages below that level, its capacity must be derated at approximately .15 ampere per volt.

The AR-1215 has been designed specifically with the unique needs of audio and video in mind. Its technology differs from that of computer-oriented voltage regulators in many important ways.
