Feature:1. Operating Principle: The controller can control the wind turbine to automatically charge the battery. When the battery is fully charged, the fan will be braked automatically by the internal circuit. When the battery voltage drops to the recovery voltage, the fan will resume charging the battery.2. Protective Function: When charging, the controller has the function of limiting voltage and current to ensure the best charging effect. At the same time, it provides maximum protection for wind turbines and batteries.3. Modular Design: The rectification and braking circuit parts of the controller are designed with an integrated module, which is further than the traditional design in terms of heat dissipation and reliability.4. 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.5. Aluminum Alloy: The controller is made of aluminum alloy material, corrosion resistance and wear resistance, comes with a long life span.Specification:Item Type: Wind Generator ControllerMaterial: Aluminum AlloyRated Battery Voltage: 12 or 24VRated Wind Turbine Capacity: 400WWind Turbine Braking Voltage: 14.5V or 29VWind Turbine Recovery Voltage: 13.5V or 27VIP Protection Level: IP67.Package List:1 x ControllerNote:Pay attention to the safety of electricity use, and the wiring must be accurate.
