The AR-Series regulators are designed specifically for any audio, video, or computer rackmount system requiring clean, filtered, and regulated AC power for optimum operation. On/off switch Output voltage selector switch (AR-1215J and AR-2306 only) Compact, lightweight unit weighs only 12 lbs. (5. 5 kg) AR-SERIES FEATURES SAFETY INFORMATION AR-1215 and AR-1215J provide nine regulated, conditioned AC outlets--eight on the rear panel and one on the front AR-1215 and AR-1215J input capacity is 15 A; output capacity is 12 to 15 A AR-2306 provides eleven regulated, conditioned AC outlets--ten on the rear panel and one on the front AR-2306 input capacity is 6 A; output capacity is 5 to 6 A Usable range for most equipment is an additional 10% above and below the ranges shown in the table below Extreme overvoltage or undervoltage causes instant shutdown, protecting equipment Extreme Voltage Shutdown indicator LED Output In Regulation indicator Ten-LED bargraph input voltmeter Fast-acting user-accessible circuit breaker protects against overload or shorts Very low stray magnetic field leakage To obtain best results from your Furman AR-1215 or AR-2306, please be sure to read this manual carefully. WARNING: To reduce the risk of electrical shock, do not expose this equipment to rain or moisture. [. . . ] Model AR-1215 produces 120 VAC: AR-1215J produces either 100 or 120 VAC; and AR-2306 produces either 220, 230, or 240 VAC. 3 A R - 1 2 1 5 A C L I N E V O LTA G E R E G U L AT O R drawing 40 to 50 watts total. DEFINITIONS Because noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be effectively reduced through use of low-pass filtering. VOLTAGE REGULATION: The AC line voltage is a number indicating the nominal electrical potential that has been adopted in a region for powering electrical equipment of all kinds. In most of North America it is 117 volts AC; in Japan, 100 volts; and in many other countries 220, 230, or 240 volts. The actual voltage can fall below or rise above this nominal level due to brownouts, power cutbacks, use of substandard wiring, and other causes. These deviations can cause poor performance or a malfunction. A regulator is a device which, through use of a transformer, corrects the voltage deviation by stepping it up or down so that it is as close as possible to the nominal level. SPIKE: A pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. Though they are usually of very short duration, the energy they contain can be considerable, enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and degrade wiring insulation. They are an unavoidable component of electric power. They are caused unpredictably by electric motors switching on or off (on the premises or outside), utility company maintenance operations, nearby lightning strikes, and other factors. Spikes (also called surges or transients) are absorbed by special components called MOV's in the AR-series to provide safe voltage levels to protect your equipment. RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower voltages and less energy than is found in spikes, but it is continuous rather than transient in nature. It is not likely to cause physical damage, but it can certainly be annoying, producing static in audio circuits, "snow" on video screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters, certain kinds of lighting, electric motors, and others. EXTREME VOLTAGE PROTECTION The AR-Series includes special circuitry to sense over- and under-voltages and positively shut down the output before possible damage is done. See the Specifications on the back page for the exact voltages at which shutdown occurs. When the input voltage exceeds the limit, the power will cut off. It will come back on automatically when the overvoltage is removed as long as the voltage has not exceeded 300V [all models]. The red LED labelled EXTREME VOLTAGE SHUTDOWN indicates the shutdown condition. The output is also shut down for extremely low input voltages. To provide protection against a catastrophic error in AC mains wiring, dangerously high voltages (those over approximately 300V) will cause an internal fuse to blow, but equipment plugged into the Voltage Regulator will not be damaged. FUSES AND CIRCUIT BREAKERS There is one fuse and one circuit breaker in the AR-Series. In the event that the unit appears to be completely dead (neither the Power switch nor any LED's light up), unplug the power cord and the load and check the breaker.
