| The 15 amp AR15 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. AR15 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 AR15 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. Many competitive voltage regulators use noiseinducing, motorized transformerbased technology. This results in large, expensive, and less reliable units which can not match the level of performance delivered by the AR15. Essentially, Furman’s advanced technology allows us to offer superior performance in a one rack space unit at a cost effective price point. The AR15 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 zerocrossing, to avoid distorting the AC waveform. (Most commercial voltage regulators using multipletapped 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 AR15 has eight outlets on the rear panel and one on the front panel. All outlets are regulated, spikesuppressed, and filtered against RFI. There are no controls except the onoff switch. A bargraph 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). LiFT (Linear Filtering Technology): 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, nonlinear 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 reboot digital presets, 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 maintenancefree 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 overvoltage 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. |
