To Surge and Protect! We can't stress the importance of regulated power enough. Not only does it protect your gear from spikes, surges, brown-outs, and ground loops, it enables it to perform as it should - with the proper power levels that it's designed to operate at, which equates to a better sound, or at very least, the quality of sound your gear is supposed to provide. The concept is exactly the same as putting low octane, unfiltered fuel into a high performance automobile; it'll run, but certainly not as well as it's meant to, and will start to show excessive signs of wear. With Furman's AR-15, you can maintain the life of your gear and boost it's performance. Furman AR-15 at a Glance:
Delivers Stable Voltage The 15 amp AR-15 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. 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. LiFT (Linear Filtering Technology) Additionally, the AR-15 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 Mode Protection circuitry (SMP). This circuit provides the highest level of power protection available. Unfortunately, traditional AC filter conditioners have been designed for unrealistic laboratory conditions. Prior technologies, whether multiple pole filter or conventional series mode, could actually harm audio and video performance more than they help, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs can actually add more than 10 dB of noise to the incoming AC line! Worse still, lost digital data, the need to re-boot digital pre-sets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman's SMP with LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground. SMP (Series Mode Protection) Furman's maintenance-free SMP surge suppression virtually eliminates service calls. Traditional surge suppression circuits "sacrifice" themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system and repair of your surge suppressor. With Furman's SMP, however, damaging transient voltages are safely absorbed, clamped and dissipated. No sacrificed parts, no service calls, no down time. Unique to Furman's SMP is its unparalleled clamping voltage. Unlike some series mode suppressors, Furman's maintenance free feature is not at the expense of potential equipment failure! While other designs offer clamping voltages that are well above 300Vpk, Furman's SMP clamps at 188Vpk, 133 VAC RMS, even when tested with multiple 6000Vpk - 3000 amp surges! This unprecedented level of protection is only available with Furman's SMP technology. Additionally, Furman's trusted over-voltage circuitry protects against all too frequent accidental connections to 208 or 240VAC, by shutting off the incoming power until the over voltage condition is corrected. Low Noise 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 one rack space unit at a cost effective price point. Outlets The AR-15 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). Furman AR-15 Features:
