[. . . ] AC LINE VOLTAGE REGULATOR AR-PRO AR SERIES AR-PRO ­ AC LINE VOLTAGE REGULATOR Congratulations on your purchase of a Furman AR-PRO AC Line Voltage Regulator. The ARPRO is the perfect accessory to any audio, video, or computer rack-mount system requiring clean, filtered, and regulated AC power for optimum operation. It is the ultimate high current regulating product for audio, video, computer, and broadcast professionals. GENERAL I N F O R M AT I O N FEATURES OF THE AR-PRO Delivers 120 VAC ±4% anywhere within capture ranges of 88 to 134 and 170 to 264 volts AC, 50/60 Hz, single phase Extends the usable voltage range for most equipment to 80 to 267 VAC Input voltmeter bar-graph with 21 LEDs Output ammeter bar-graph with 21 LEDs indicates low, normal, or high output voltage/current Fourteen regulated, conditioned outlets (2 front, 12 rear) Input capacity 30 amps; output capacity 22. 5 to 30 amps Provision for remote turn-on/turn-off; multiple units may be turned on simultaneously or in a delayed sequence Multiple-stage transient (spike) suppression Multiple-stage RFI filtering Low stray magnetic field leakage Compact 3. 5" rack-mount unit weighs only 50 lbs (23 kg) READ THIS FIRST! 1. Carefully inspect your AR-PRO for signs of damage that may have occurred in shipping. [. . . ] See the section on Remote/Delayed Operation later in this manual for details. Note: No connections or jumpers are needed for normal AR-PRO operation. REGULATED OUTLETS: There are 14 regulated outlets on the AR-PRO, two in front and the balance in the rear. While the combined load formed by all equipment plugged into all 14 outlets may not exceed 30 amps, the load on any one individual outlet may not exceed 15 amps, which is the maximum permissible for the type of connector used. REAR PANEL FEATURES INPUT CONNECTOR: This 4-pin twist-lock connector is rated at 30 amperes for 120/240 volt service. See the Installation section for information on wiring a supply cable. 120V/100V SWITCH (Model AR-PRO-J Remote Turn On Barrier Output Voltage Selector Switch (J Version Only) 30 A Inlet (12) Switched Regulated Outlets -7- AR-PRO ­ AC LINE VOLTAGE REGULATOR AR-PRO QUESTIONS AND ANSWERS Q. What happens if the Input Select switch is set to the wrong position and power is applied to the AR-PRO?In most cases, power will not reach the AR-PRO's input and it will appear to be dead. Normal operation will resume as soon as the switch is restored to the correct position. The only exception to this rule would be in the event that a 4-wire power cable is used and is connected to a USA source of 240V. In that case, the wrong setting will result in the AR-PRO running off half the line (120V-i. The AR-PRO will function normally, but there is a minor disadvantage to running this way. In no case will an incorrect setting of the Input Select switch result in damage. If both 120V and 240V are available, which is better to use?Since an output of 120V at 30 amps requires only 15 amps in the supply cable at 240V, you can use a lighter gauge of wire in the supply cable (see section on Installation for details). Also, the smaller current necessary for high range (240V) operation allows all the internal components of the AR-PRO to run cooler and therefore may prolong its service life. Will the AR-PRO protect my equipment from lightning strikes?If lightning strikes a distant power line and causes a relatively small disturbance to reach your location, the spike suppressors in the AR-PRO will absorb the excess voltage invisibly and harmlessly. However, if lightning strikes the actual building where the AR-PRO is installed (or somewhere very nearby), equipment damage may be unavoidable due to the extremely high voltage and current present. If this does occur, most likely damage to the AR-PRO itself will be limited to the spike suppression components (called varistors or MOVs), which should be a relatively minor repair. Any AR-PRO known to have taken a direct lightning hit should be checked by a qualified technician or the Furman factory to determine whether the MOVs need replacement. If they are damaged, the AR-PRO may appear to be working normally, but its vital spike-suppression capability will be eliminated.
