Features: The LED indicates the working state of the circuit, simple, intuitive and clear. The controller can control the wind turbine to automatically charge the battery. Automatic brakes and manual brakes complement each other to meet the different needs of customers. Comprehensive waterproof protection, not easy to be corrosive and get damaged in humid conditions, more reliable. Adopts imported electronic components and industrial-grade chips, can use in the high temperature environment of -35-70. Unique reverse protection circuit. No need to replace the fuse due to improper operation of the battery reverse, as long as the positive and negative polarity can be re-connected. Specification: Condition: 100% Brand New Material: Plastic Color: Black Battery Rated Voltage: 12V, 24V(optional) Rated Power: 600W Working Temperature: -35~75 Display: LED Quiescent Current: 20mA Protection Grade: IP67 Size: Approx. 97 * 76 * 21mm / 3.8 * 3.0 * 0.8" Package Weight: Approx. 260g Package Included: 1 X Wind Turbine Controller Notice: 1. Make sure the output voltage of the wind turbine is consistent with the rated voltage of the battery. 2. First connect the positive and negative poles of the battery, then connect the three-phase voltage output of wind turbine. 3. Please follow instructions carefully to connect the battery and the wind generator to the controller. The reverse polarity or the wrong position will cause the system to work abnormally and even cause damage to the system components. 4. Although the controller has taken protective measures against a variety of possible contingencies, it is strongly recommended that users strictly comply with operating procedures to prevent significant damage to batteries and controllers. Wiring Method: 1. Connect the battery "+" and "-" respectively to the positive and negative terminals of controller's battery . 2. Connect three-phase output voltage of wind generator respectively to the three-phase voltage input terminal of the controller wind turbine. 3. When you need to manually brake, connect the thin line to the positive pole of battery, you can achieve manual braking. Indicator State: 1. When the controller green power (BATTERY) indicator is on, it indicates that the battery is connected normally. 2. When the controller green wind turbine (WIND) indicator flashes, it shows that the wind generator is connected, and the speed of flickering reflects the wind turbine speed. 3. When the controller red (BRAKE) indicator is on, in shows the battery is full, the wind generator automatically brakes because of over-current protection, or it is in the state of manual braking.
