Furman AR20II Voltage Regulator
FURMAN AR20II VOLTAGE REGULATOR
The AR-20 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 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.
Additionally, the AR-20 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!
Features:
- Precise Voltage Regulation delivers a consistent, stable 120 Volts output to safely power connected equipment and optimize performance regardless of fluctuations in the input level
- Series Multi-Stage Protection Plus (SMP+) for virtually maintenance free protection from surges and spikes. No sacrificed parts, no service calls, no downtime!
- Furman’s unequaled Linear Filtering Technology (LiFT) rids systems of AC line noise for consistent audio/video clarity
- Automatic Extreme Voltage Shutdown (E.V.S.) powers down equipment during a prolonged or extreme over-voltage
- Ultra-low noise torodial autoformer assures no mechanical noise or hum-inducing magnetic field
- Fourteen AC outlets with two bi-directionally filtered banks to isolate digital and analog components
- Output capacity 20 amps
Many competitive voltage regulators use noise-inducing, motorized transformer-based technology. This results in large, expensive, and less reliable units which cannot match the level of performance delivered by the AR-20. Essentially, Furman’s advanced technology allows us to offer superior performance in a cost effective unit.
The AR-20’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. (Most commercial voltage regulators usingmultiple-tapped transformers switch taps at uncontrolled times, thereby creating voltage spikes, and often creating clicks that can leak into the audio.)
The AR-20 has twelve 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 twelve 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 rack mount chassis, 3.5? high and 17.125? deep with rack ears (14.125? deep without rack ears).
