Operating Principle: The controller can control the wind turbine to automatically charge the battery. When the battery is fully , the fan will be braked automatically by the internal circuit. When the battery voltage to the voltage, the fan will resume charging the battery.Protective Function: When charging, the controller has the function of limiting voltage and current to the charging effect. At the same time, it provides maximum protection for wind turbines and batteries.Modular Design: The rectification and circuit parts of the controller are designed with an integrated module, which is further than the terms of heat dissipation and reliability.Waterproof Performance: This controller adopts more than IP67 fully sealed and completely waterproof design, which can be used normally for a long time even in water.Aluminum Alloy: The controller is made of aluminum alloy material, corrosion resistance and wear resistance, comes with a span.Item Type: Wind Generator ControllerRated Battery Voltage: 12 or 24VRated Wind Turbine Capacity: 400WWind Turbine Voltage: 14.5V or 29VWind Turbine Voltage: 13.5V or 27VIP Protection Level: IP67Note: Pay attention to the safety of electricity use, and the wiring must be .color:As shownMaterial:Aluminum AlloyPackage Contents:1 x ControllerOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
