FURMAN AR-15 II Voltage Regulator with Linear Filtering Technology (LiFT)

Item# AR-15II

Product Description

The 15 amp AR-15 II 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. AR-15 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.

Additionally, the AR-15 II is the only regulator that filters and purifies AC power, reducing line noise and ensuring optimum performance. Not only will your equipment perform better with Furman’s advanced filtering technology, but it will also be fully protected by our exclusive Series Multi-stage Protection Plus circuitry (SMP+), which features Linear Filter Technology (LiFT) and Extreme Voltage Shutdown (EVS) with high current TVZ-MOV. This circuit provides the highest level of power protection available.

Many competitive voltage regulators use noise-inducing, motorized transformer-based technology. This results in large, expensive, and less reliable units which can not match the level of performance delivered by the AR-15. Essentially, Furman’s advanced technology allows us to offer superior performance in a single rack space unit at a cost effective price point.

The AR-15 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 switched electronically 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.) The design is not sensitive to small errors in line frequency, making it ideal for use with generators.

The AR-15 II has eight outlets on the rear panel and one on the front panel. All outlets are regulated, spike-suppressed, and filtered against RFI. There are no controls except the 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).
