Feature 1 The controller can control wind turbines to charge the battery automatically. 2 When the battery is fully charged, brake can be controlled automatically by the interior circuit. 3 When the battery voltage drops to restore voltage level, wind turbine can automatically recover to the battery charging, so as to protect the wind turbine and the battery. 4 With the independent intellectual property rights of modular design, which makes the performance of the whole system to get the biggest safeguard. 5 Rectification of this controller and braking circuit part has adopted the integration module design, better heat dissipation and reliability than the traditional design. Features: 1. The controller can control wind turbines to charge the battery automatically. 2. When the battery is fully charged, brake can be controlled automatically by the interior circuit. 3. When the battery voltage drops to restore voltage level, wind turbine can automatically recover to the battery charging, so as to protect the wind turbine and the battery. 2. With the independent intellectual property rights of modular design, which makes the performance of the whole system to get the biggest safeguard. 5. Rectification of this controller and braking circuit part has adopted the integration module design, better heat dissipation and reliability than the traditional design. 6. Comprehensive waterproof protection. The protection grade reaches the IP67 above, which enables the controller can steadily work normally in water for a long time. Specifications: Model Number: FW03-12 Battery Rated Voltage: 12V Wind Generator Rated Power: 300W Brakes Start Voltage: 15V Brake Recovery Voltage: 13.5V Display: LED Working Temperature and Humidity Range: -35~+75 Controller Shell Size: Approx. 100*87*28mm/3.9*3.4*1.1in Quiescent Current: 15 mA Waterproof: IP67 Connection: Connect the positive and negative terminals of the battery to the positive (red line) and negative (black line) terminals of the controller, respectively. Connect the three-phase output voltage of the wind turbine to the three-phase input (green line) terminal of the controller fan, respectively. Package List: 1 * Wind Charge Controller Notes: 1. Please make sure that the output voltage of the wind generator is consistent with the rated voltage of the battery. 2. Wiring according to the following sequence, first connect the positive and negative terminals of the battery, and then connect the three-phase voltage output of the wind generator. 3. Please connect the battery and the wind turbine to the controller in strict accordance with the requirements of the instructions. Connecting the reverse polarity or the wrong position will lead to the abnormal operation of the system, or even lead to the complete damage of the controller.
