Features: _x000D_ 1. The controller can control wind turbines to charge the battery automatically. _x000D_ 2. When the battery is fully charged, brake can be controlled automatically by the interior circuit. _x000D_ 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. _x000D_ 2. With the independent intellectual property rights of modular design, which makes the performance of the whole system to get the biggest safeguard. _x000D_ 5. Rectification of this controller and braking circuit part has adopted the integration module design, better heat dissipation and reliability than the traditional design. _x000D_ 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. _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Model Number: FW03-12 _x000D_ Battery Rated Voltage: 12V _x000D_ Wind Generator Rated Power: 300W _x000D_ Brakes Start Voltage: 15V _x000D_ Brake Recovery Voltage: 13.5V _x000D_ Display: LED _x000D_ Working Temperature and Humidity Range: -35~+75 _x000D_ Controller Shell Size: Approx. 100*87*28mm/3.9*3.4*1.1in _x000D_ Quiescent Current: 15 mA _x000D_ Waterproof: IP67 _x000D_ Connection: _x000D_ Connect the positive and negative terminals of the battery to the positive (red line) and negative (black line) terminals of the controller, respectively. _x000D_ Connect the three-phase output voltage of the wind turbine to the three-phase input (green line) terminal of the controller fan, respectively. _x000D_ _x000D_ _x000D_ Package List: _x000D_ 1 * Wind Charge Controller _x000D_ _x000D_ _x000D_ Notes: _x000D_ 1. Please make sure that the output voltage of the wind generator is consistent with the rated voltage of the battery. _x000D_ 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. _x000D_ 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.
