[. . . ] AIR-X Page 1 of 3 SWWP Products AIR-X Wind Module Introducing the latest evolution in small wind turbines. The AIR-X builds upon what has made AIR the world's #1 selling small wind turbine with new technology previously found only in today's state-ofthe-art mega-watt-class wind turbines. AIR-X Marine Features Design Improvements Applications Specifications Tower Kits Testimonials All of these features are primarily found within the body of the turbine. [. . . ] This results in a much quieter wind turbine. In high winds, the AIR-X will continue to produce power at a reduced level until the wind decreases, at which point maximum potential output will resume. The Benefit: Quieter and neighbor friendly wind turbine. Improved battery charging: Previous AIR designs required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be adequately absorbed. The AIR-X's charge controller periodically stops charging, reads the battery voltage, compares it to the voltage setting and if the battery is charged, it completely shuts off all current going to the battery. This function is performed within a few milliseconds. The closer the battery is to reaching its full state of charge, the more often the AIR-X's circuit repeats this action. This means any size battery bank from 25 to 25, 000 amp hours or higher can be charged safely. When the battery has reached its charged state, the AIR-X will slow to an almost complete stop. http://www. windenergy. com/PRODUCTS/airxland. html 5/26/2004 AIR-X Only when the battery has dropped below its voltage set point will it startup and resume charging. The Benefit: Extended battery life, no overcharging. Lower stress design: AIR-X limits power on the input side of the electronics by controlling the torque from the blades. The power no longer has to be dissipated by the electronics resulting in lower stress on the circuit, bearings and other materials. Furthermore, stress on wind turbines occurs primarily in high winds.
