Though the need for pristine AC power is nothing new, the IT-Reference 20's technology and its unique implementation are revolutionary and without peer. The extreme AC demands encountered in the professional audio/video arena have required technological developments far in excess of typical home theater/audiophile power products. In studios, live sound, and broadcast facilities, breakdown is unacceptable. [. . . ] It is rare, in fact, for large power amplifiers to draw more than 4 Amps continuously. For superior performance, it is vital that an AC filter possess extraordinarily low impedance, and have the capability to pass peak current demands far in excess of the RMS (continuous) current rating. The IT-Reference 20 was designed to more than meet this demand. Additionally, our Power Correction Circuitry effectively creates a current reserve in excess of 80 amps peak up-charge that is cleaner and faster than a dedicated line from your local power station. This feature eliminates any concern towards the current 5 compression that can result from typical power conditioners, and the peak power reservoir benefits any power amplifiers performance dramatically. Note about Power Factor Correction and Current Consumption When power correction technology is employed with even the most sophisticated circuit breakers, it effectively adds to the perceived current load. Though the ITReference 20 was designed for steady 20 Amp operation, and peak current demands many times that, the maximum total continuous current draw may be limited to a range between 1500 - 2100 Watts per IT-Reference 20 employed. The RMS current available before the circuit breaker trips varies due to what is referred to as a vector load. Simply put, the type of power supplies or electronic circuits connected to the IT-Reference 20 will have an effect on its circuit breakers perceived current load, and therefore, when it will trip. Though the benefits of power factor correction far outweigh the small reduction in continuous current draw, this must be accounted for when constructing a large system with high current demands. The total continuous current draw of most electronic components is typically listed in Watts by their AC input cord or AC connector. Watt ratings are simply added to determine the total system RMS current draw. It should also be noted that the IT- Reference 20's power correction circuitry has no actual effect on the power drawn from your utilities' power meter. Then, Though it will function flawlessly right from its add each piece of equipment until the GFCI trips. shipping carton, the performance of its circuit Contact the manufacturer of the suspect unit for parts will improve after approximately two possible solutions. weeks of continuous use or "break-in. " Testing the IT-Reference 20's GFCI once a Ground Fault Interrupter (GFCI) year is recommended. Simply press the button The IT- Reference 20's "Discrete Symmetrical marked "TEST ­ GFCI protected. " If the GFCI Filtered AC outlets" incorporate a balanced is functioning properly, this will cause the main AC power output, whereby both the neutral circuit breaker/power switch to trip and cut and positive leads of the AC cable run at 60 off power. After verifying the GFCI's proper Volts AC in opposing polarity, referenced to operation, simply restore power by switching the ground (0 Volts AC). This is but one of the Circuit Breaker/Power Switch to the ON position. IT- Reference 20's advantages over other ACfilter/protection designs. AC Transient Voltage Surge Suppression The IT-Reference 20 is capable of suppressing Though virtually all domestically produced virtually any instantaneous voltage surge from electronic equipment is designed to detect lightning or commercial power companies. electrical shorts and other potentially This is due in part to the mammoth reactive dangerous equipment problems in the elements in the IT-Reference 20's AC power Line lead referenced to its Neutral, this is correction circuitry.
