AIR-X 400 LAND 12 V Wind Turbine – 400 W with integrated regulator

The AIR-X 400 LAND is a terrestrial horizontal axis wind turbine designed for charging a 12 V battery bank. It combines a rotor with three carbon-reinforced composite blades with an integrated charge regulator in the nacelle.

Its announced nominal power is 400 W for a wind speed of 12.5 m/s, or 45 km/h. It can supplement the power supply of a cabin, an isolated site, or low-voltage equipment when wind exposure is suitable.

Integrated regulation and rotation control

The microprocessor internal regulator monitors the battery charge and adjusts the operation of the wind turbine. When the batteries reach their charge level, the electronics reduce production and slow down the rotation.

Electronic control also intervenes in strong winds to limit the turbine speed and mechanical stresses. These functions must be used in accordance with the AIR-X manual and the type of batteries installed.

Installation on 12 V batteries

The energy produced is intended for storage in 12 V batteries compatible with the wind turbine's charge settings. To power devices at 230 V AC, a suitable 12 V/230 V converter is necessary.

The mast, batteries, and converter are not provided. The support, wiring, and protections must be sized for the installation and comply with the equipment manual.

The power actually available varies with the wind at the rotor level, installation height, obstacles, and electrical losses. The announced 400 W does not correspond to permanent production.
