Furman AR-1220 AC Line Voltage Regulator, NEW

Description: This sale is for a New, out of box, never installed, Furman Model 1220 Power Conditioner. It comes with an heavy duty, 12 gauge, AC power cord, but you must install the appropriate AC connector yourself. (It could be used with standard 15 amp connector, or a variety of 20 amp connectors). There are minor handling scratches on the chassis. This 35 pound beast actually changes and corrects the line voltage ... unlike the many 'surge protectors' and multi output boxes. This is a serious, no-nonsense piece of high quality equipment ideal for use in on-the-road PA systems. The Furman AR-1220 AC Line Voltage Regulator has been designed specifically with the unique needs of audio and video in mind! The 20 amp AR-1220 protects audio, video, computer and other electronic equipment from problems caused by AC line voltage irregularities - sags, brownouts, or over-voltages that can cause sensitive digital equipment to malfunction, or, in extreme cases, to sustain damage. The AR-1220 accepts input voltages from 97V to 141V and transforms them to a steady, stable 120 VAC (±5V) output. Voltages beyond that range may also be converted to usable levels, depending on how far out of range they are. The AR-1220 can handle loads totaling up to 20 amps as long as the input voltage is above 124 volts. Unique technology optimized for audio and video use The AR-1220's technology differs from that of computer-oriented voltage regulators in many important ways: the AR-1220 does not use a ferro-resonant transformer, so it's not heavy and bulky, doesn't radiate a large magnetic field, and isn't too frequency-sensitive to be usable with generators. Instead, it uses a design based on an eight-tap toroidal autoformer. The toroidal design assures minimal leakage of stray magnetic fields. The AR-1220 circuitry monitors the incoming line voltage with each cycle, comparing it to an extremely precise voltage reference, accurate to ±0.15%. If a voltage fluctuation requires that a different tap be selected, the new tap is electronically switched exactly at the zero-crossing, to avoid distorting the AC waveform. (Most commercial voltage regulators using multiple-tapped transformers switch taps at uncontrolled times, thereby creating voltage spikes, and often creating clicks that can leak into the audio.) Hysteresis of 1.5V in the switching circuits avoids "chatter." The design is not sensitive to small errors in line frequency, making the AR-1220 ideal for use with generators. The AR-1220 also features power conditioning that is truly in a class by itself, thanks to the quantity, quality and configuration of the overvoltage suppression devices used. These include MOV's, high voltage inductors and capacitors, and precise high-inrush magnetic circuit breakers. This unique combination can safely divert large spikes as well as filter audible high frequency noise. An additional feature, Extreme Voltage Shutdown, senses dangerously high or low voltages and shuts down the output before any damage is done. The output remains off until the over-voltage or under-voltage is removed, with an LED indicating the shutdown condition. This invaluable feature provides positive protection to your equipment from accidental connection to incorrect line voltages (for example, 220V when 120V is expected - a not uncommon hazard in the entertainment industries. Plenty of outlets and simple controls The AR-1220 has 12 outlets on the rear panel, and two on the front panel. All outlets are regulated, spike-suppressed, and filtered against RFI with a 3-pole filter. There are no controls except the circuit breaker/on-off switch. A 10- LED bar-graph meter indicates input voltage, while another LED indicates "In Regulation" status. Also provided is a 10-LED bar graph meter to indicate output current. The unit is housed in a compact, 2U rack-mount chassis and weighs only 35 lbs.

He had a serious audio hobby, some might call him a gear slut. He was also very fastidious. His equipment all looks like it just came out of the box. This unit has never seen nightclub use or touring use. There are no known visible flaws, damaged or missing parts. This is one of many units we are posting ... all in near mint condition, at very low prices. This unit will ship PREPAID to US Customers in the 48 states continental states.
