AR-20 SERIES II DESCRIPTION |
|
Premium-quality Protection for Your Electronic Gear The Furman AR-20 Series II delivers a stable stream of AC power to protect equipment from problems caused by AC line voltage irregularities such as sags, brownouts, or over-voltages - all of which can cause sensitive electronic equipment to malfunction or sustain damage. Featuring a generous 20-amp capacity, the AR-20 Series II accepts any input voltage from 97V to 141V and transforms it to a constant 120V. Voltages beyond this range are also converted to usable levels, unless they are extremely far out of range, in which case the unit will automatically power down to prevent equipment damage. Furman AR-20 Series II Voltage Regulator at a Glance:
Regulates, filters, and purifies AC power The AR-20 Series II is the only 20-amp regulator that filters and purifies AC power, reducing line noise linearly and ensuring optimum performance. Your equipment will perform at optimum levels and will be fully protected from spikes and surges by Furman's exclusive SMP+ technology. This virtually maintenance-free surge suppression system incorporates Linear Filtering Technology (LiFT), Extreme Voltage Shutdown (E.V.S.), and high current TVZ MOVs to provide the highest level of power protection available - all without the need for servicing or replacement of the unit. Just install it in your rack and forget about it! Delivers stable voltage with precision The AR-20 Series II's circuitry monitors the incoming line voltage with each cycle, comparing it to an extremely precise voltage reference, accurate to ±0.15%. The design is not sensitive to small errors in line frequency, making it ideal for use with generators. 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. Regulated, spike-suppressed outlets The AR-20 Series II has 12 outlets on the rear panel and two convenience outlets on the front panel. All outlets are regulated, spike-suppressed, and filtered against radio frequency and electromagnetic interference. The 12 rear outlets are divided into two separate banks with bi-directional filtering for either analog or digital components. There are no controls except for the on-off switch. A digital meter 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, dual-space rackmount chassis. Employs Furman's Series Multi-stage Protection Plus SMP+ is Furman's proprietary surge suppression and noise filtration system. Designed over a period of two years by Furman's engineering team, SMP+ is composed of three separate and distinct technologies which work together in a precisely tuned circuit to filter or "clean" the incoming power and to protect connected equipment from potentially damaging AC events. These technologies are Linear Filtering, Series Multi-Stage Protection, and Extreme Voltage Shutdown. Linear Filtering Technology for noise-free AC Unfortunately, traditional AC filter conditioners have been designed for unrealistic laboratory conditions. Prior technologies 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 10dB of noise to the incoming AC line! Worse still, lost digital data, the need to re-boot digital presets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman's LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground. SMP clamps over-voltages without sacrificing itself Traditional surge suppression relies on circuits that "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 downtime. Also unique to Furman's SMP+ is its unparalleled clamping voltage. 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. Extreme Voltage Shutdown powers down connected gear safely When voltage rises to extreme levels because of a lost neutral line or an accidental connection to 208 or 240 VAC, Furman's Extreme Voltage Shutdown kicks in, automatically powering down all equipment quickly and safely in order to prevent damage from occurring. An indicator LED will then illuminate, alerting you to the situation until the over voltage condition is corrected. Furman AR-20 Series II Voltage Regulator Features:
