User manual FURMAN AR1230

[. . . ] Two additional 15A outlets are located on the front. All outlets are regulated, spike-suppressed, and EMI/RFI filtered. There are no controls except an on-off breaker switch (except "J" version, which has a 100/120V switch. ) 1 AR-1230 A C L I N E V O LTA G E R E G U L AT O R FUSES AND CIRCUIT BREAKERS There are three fuses and one fast-acting magnetic circuit breaker in the AR-1230. A precision 30 amp magnetic circuit breaker is used as the on/off switch. [. . . ] Your equipment should work normally when this light is on, and often will work satisfactorily even when the OUTPUT IN REGULATION LED is off. If you wish to monitor your AR-1230's output voltage more 2 AR-1230 A C L I N E V O LTA G E R E G U L AT O R 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. 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. precisely, you may want to use a Furman PL-PLUS Power Conditioner and Light Module in conjunction with it. The PL-PLUS is the perfect complement to a Furman Voltage Regulator to assist in rack power distribution. It offers a 20-LED bar-graph line voltage meter to monitor the incoming line (the Voltage Regulator output), twin slide-out, swiveling lights with a dimmer control for equipment illumination, and eight AC outlets with their own spike/surge protection and RFI filtering. DEFINITIONS 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 117-120 volts AC; in Japan, 100 volts; and in many other countries 220, 230, or 240V. 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 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 3 OUTPUT CURRENT MONITORING The AR-1230's ammeter reads AC current from 0 to 30 amps, in 3-amp steps. Currents above the 30 amp limit read red, with yellow indicating a warning zone. Please keep in mind that the ammeter may not read at all if the total load connected is less than 2 amps (240 watts). This is a likely occurrence if only relatively low power, signal processing-type equipment is connected.

We suggest that you save the original packaging and use it to ship the product for servicing. Also, please enclose a note giving your name, address, phone number and a description of the problem. NOTE: All equipment being returned for repair must have a Return Authorization (RA) Number. [. . . ]
