OVERVIEW
The AR-3000 is the perfect accessory to any audio, video, or computer and peripherals rack-mount system requiring clean, filtered, and regulated AC power for optimum operation.
The regulator accepts an input voltage over a wide AC voltage range and convert it to the required standard stable output voltage (110Vac +/-5V); voltages outside this range of approximately ± 10% can be converted to usable levels, depending on considered usable devices.
DESCRIPTION
The AR-3000 design is based on an 11-taps Toroidal autotransformer. The Toroidal design assures minimal leakage of stray magnetic fields, and, because of its high efficiency, a very compact size for its rating. The Voltage Regulator’s circuitry monitors the incoming line voltage with each cycle, and compares this to a precise voltage reference (Accuracy is ± 0.15%).
If a voltage fluctuation requires that a different tap be selected, the new tap is electronically switched at a precise moment, so as to minimize distortion of the AC waveform. If necessary, the AR-3000 can switch taps as often as once each cycle.
Most commercial voltage regulators using multiple-tapped transformers switch taps at random times, thereby creating voltage spikes and clicks that can leak into the audio! Hysteresis in the tap switching points prevents “chatter” or unnecessary switching back and forth between adjacent taps. Unlike voltage regulators that employ Ferro-resonant transformers, the AR-3000 is not sensitive to small errors in line frequency, making it ideal for use with generators.
Because its Toroidal transformer design minimizes stray magnetic fields, the AR-3000 may be positioned near most other equipment without concern that the neighboring equipment will be influenced by magnetic leakage from the transformer. It is suggested that the AR-3000 be located either at the top or bottom of the rack.
