AIR-X Wind Module
A
ll of these features are primarily found within the body of the turbine.
The new microprocessor based turbine controller results in increased
p
erformance, improved battery charging capability, greater reliability
and the reduction of “flutter” noise from the machine.
The controller allows for peak-power tracking of the wind by optimizing
the alternator's output on all points of the cubic curve and then
efficiently delivers the energy to the battery. The turbine’s smart
controller allows it to actually control blade rotation speed thus
eliminating the buzzing noise commonly found with the AIR 403 and
303 in high winds. Furthermore, a new series of carbon-reinforced
blades with a modified pitch angle further increases power production.
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
p
reviously found only in today's stat
e
-of-
the-art mega-watt-class wind turbines.
Much Lower Noise: Previous AIR wind
modules relied on their aero-elastic blade
design for protection in high winds. This
caused a loud flutter noise in winds above 35
mph (16 m/s). AIR-X’s circuit monitors the wind
speed and electronically slows the blades as it
reaches its rated output preventing it from
going into flutter. 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.

Specifications
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. Under these conditions, the electronic stall
design reduces the blade speed to 600 rpm, thereby significantly reducing
turbine and tower loading while still producing power.
What's New in the AIR-X?
zNew microprocessor-based controller.
zLower torque bearings allow for improved startup.
zNew series of carbon reinforced blades.
zMore robust tower clamp and yaw assembly for stronger and more
secure tower mounting.
