Furman AR1215 Rack Mount Voltage RegulatorThe Furman AR1215 Rack Mount Voltage Regulator is intended to protect electronic gear from problems caused by AC line voltage irregularities that can damage equipment.
The AR-1215 accepts voltages from 97 to 141 volts and converts them to a constant 120 volts, +/-5V. It can handle loads up to 15 amps, as long as the input voltage is above 124 volts. Delivers a stable 120V +/-5VAC, eight outlets on the rear panel, 1 on the front. Equipment is protected by instant shutdown when voltage is out of range. Low stray magnetic field leakage-ideal for audio/video applications. Manufactured in the USA.

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.
For example:
The AR-1215 does not use a ferro-resonant transformer, which would be heavy and bulky, radiate a large magnetic field, and be too frequency-sensitive to be usable with generators. Instead, it uses a use a design based on an eight-tap toroidal autoformer. The toroidal design assures minimal leakage of stray magnetic fields.
The AR-1215 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 them ideal for use with generators.
The AR-1215 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 overvoltage or undervoltage 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.)
The AR-1215 has eight outlets on the rear panel, and one 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 bar-graph meter comprised of 10 LED's indicates input voltage, while another LED indicates
In Regulation status (i.e., that the output voltage is within ±5V of 120V.) The unit is housed in a compact, single-space rack-mount chassis, 1.75 inches high and 8 inches deep (8.9 x 43.2 cm) and weighs only 12 pounds (5 kg).
About Furman Power and Sound Products
Furman Sound has been producing high-quality, professional products since 1974. Our products fall into two broad categories: the audio and video signal processors (on which the company was founded) and the innovative AC power conditioning and distribution products for which we have are best known. Applications for these products are no longer limited to music, but also span a wide range of markets. Our highly acclaimed CE line, established in 2001, incorporates a complete line of AC power management products specifically engineered for today's home theater systems. Additional applications for our Professional Audio/Video products include sound reinforcement, home and professional recording, post production, broadcast systems, telecommunications, and data processing.
Recently we were proud to introduce the next generation in power conditioning technology: Series II. All Series II units feature our revolutionary Series Multi-Stage Protection Plus (SMP+) circuit. Developed over a period of two years by our highly skilled team of engineers, our new circuit incorporates our exclusive Linear Filter Technology (LiFT) and Extreme Voltage Shutdown (E.V.S.), making it the most advanced power-conditioning system available. SMP+ can be found in all Series II and Power Factor units.
We at Furman are proud of our 32 year history, but are focused on the future and our commitment to stretch the bounds of technology to provide the most advanced power purification solutions for any application.
