Features:This controller controls the wind turbine to automatically charge the battery. When the battery is full, the fan is braked by the internal circuit automatic control. When the battery voltage drops to the recovery voltage, the fan resumes charging the battery, thus protecting the fan and the battery. The rectifier and brake circuit part of the controller adopts integrated module design. Comprehensive waterproof protection. This kind of controller adopts full seal completely waterproof design, protection grade reaches the IP67 above, even in water can normal use for a long time, improve the reliability. Intelligent, modular design, simple structure, powerful functions; Industrial grade high-quality components and strict manufacturing techniques, which is suitable for relatively harsh working environments such as low temperature. It also has reliable performance and long service life. Suitable for fishing boat, street lamp, household, monitoring, small mobile base station, etc. Specification:Condition: 100% Brand NewModel: FY600Battery Rated Voltage: 12/24VWind Turbine Rated Power: 400W, 500W, 600W (Optional)Brake Start Voltage (Factory Value): 14.5V/29VBrake Recovery Voltage (Factory Value): 13.5V/27VDisplay Mode: LED (Light-Emitting Diode Display)Working Temperature: -35 ~ +75 Humidity: 85%RHQuiescent Current: 15 mAProtection Level: IP67Size: Approx. 100 * 87 * 28mm / 3.9 * 3.4 * 1.1inPackage Weight: Approx. 300gPackage list:1 * Wind Turbine Controller
