What is the Advantage of the D-400 Over Other Wind Generators?
The D-400 is a wind generator, designed for a variety of marine, rooftop or terrestrial applications. It is exceptionally quiet and vibration-free in operation, qualities that are of paramount importance for any wind generator operating in close proximity to people.
The D-400 features a powerful 3-phase alternator, and computer-designed rotor blades optimized for low speed and very quiet user-friendly operation.
This innovative machine is extremely efficient in low wind speeds, yet is capable of sustained high power outputs of 500 watts and more in higher winds (see Cameron Murray's comments below).
Distinctive and elegant in design, the D-400 is superbly engineered for long, trouble-free service, and is available in either 12, 24, 48 and 72 volt variants.
Typical D-400 Output
10 knots wind speed produces 40 watts
15 knots wind speed produces 120 watts
20 knots wind speed produces 190 watts
25 knots wind speed produces 280 watts
32 knots wind speed produces 400 watts
NOTE: These figures are representative of performance at sea level when operating in an open, turbulence-free site.
