Though the need for pristine AC power is nothing new, the IT-Reference 15'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. [. . . ] 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 15's power correction circuitry has no actual effect on the power drawn from your utilities' power meter. The IT-Reference 15 draws a mere 8. 5 Watts independent of other components, so it may be left on at all times. When power correction technology is employed with even the most sophisticated circuit breakers, it effectively adds to the perceived current load. Though the ITReference 15 was designed for steady 15 Amp operation, and peak current demands many times that, the maximum total continuous current draw may be limited to a range between 1300 - 1700 Watts per IT-Reference 15 employed. The RMS current available before the circuit 5 Note about Power Factor Correction and Current Consumption When power is first applied to the IT-Reference 15, (the front panel breaker- power toggle must be switched to the "on" position) the Soft Start feature is activated. There is an audible "clack" when the IT-Reference is first turned on or off. This sound is produced by the Soft Start circuit's 30 Amp relay engaging or disengaging. There is virtually nothing in the IT-Reference 15's construction, design, or componentry to wear over the life time of the product, and there is no power draw from your electric service meter aside from the LED power indicator, relay, and GFCI protection circuit. For this reason the IT-Reference 15 may Soft Start - Continuous Use and Break-In Time IT-REFERENCE 15 OWNER'S MANUAL be left with its power engaged permanently at a cost of pennies per month. This is an added benefit, as many audio/videophiles find performance improves significantly when leaving low-powered components permanently charged (turned on). In fact, this is true of the IT- Reference 15. Though it will function flawlessly right from its shipping carton, the performance of its circuit parts will improve after approximately two weeks of continuous use or "break-in. " The Furman GFCI detects any imbalance in the current flowing in the two hot legs. The missing current is presumed to be flowing through the ground conductor (the round pin on an AC outlet). Ground current often indicates a dangerous partial or full short circuit. Upon initially applying power to these units, the Extreme Voltage indicator LED will light if the input voltage is above the extreme voltage cutoff, and power will not be applied to the unit's 6 Extreme Voltage Shutdown Indicator: IT-REFERENCE 15 OWNER'S MANUAL outlets. If the unit has been operating with an acceptable input voltage and subsequently that voltage exceeds 137V, it will shut off power to the outlet and the Extreme Voltage LED will light. suppressors are in-line, they will require an additional cable to connect from their output to the control device requiring protection. All in-line surge suppressors feature our exclusive ground contamination free technology. This aids in eliminating audio buzzing, and the video hum-bars that can result from typical in-line suppressors. Further, our cable and satellite suppressors are TIVO friendly as well as HD-Digital Television ready.
