This wind power controller is compact in size, ensuring simple wiring and easy operation, and has a wide ranges of applications. It can control the wind power to automatically recharge the battery. The rectification and braking circuit parts of the controller are designed with an integrated module, which goes further than the traditional designs in terms of heat dissipation and reliability. There are six Specifications available, you can choose from BLW12/24-400, BLW12/24-500, BLW12/24-800, BLW24-10, BLW48-10, BLW48-400 depending on your needs. Features: Easy to Use: The wind power controller is compact in size, ensuring simple wiring and easy operation, and has a wide ranges of applications. Aluminum Alloy Material: The controller housing is made of aluminum alloy material, which is corrosion-resistant and wear-resistant, and has a long lifespan. High Stability: With nice heat dissipation effects, the controller can maintain stable operating performance. Main Purpose: The controller can control the wind power to automatically recharge the battery. When the battery is fully charged, the fan will be controlled by the internal circuit to brake the motor automatically. When the battery voltage drops to the recovery voltage, the fan will resume charging the battery. Modular Design: The rectification and braking circuit parts of the controller are designed with an integrated module, which goes further than the traditional designs in terms of heat dissipation and reliability. IP67 Comprehensive Waterproof: The controller Features a fully sealed and waterproof design, with an IP67 or higher protecting level, so it can be used normally for a long time even in water, and its stability and reliability are greatly improved. 6 Specifications Optional: There are six Specifications available, you can choose from BLW12/24-400, BLW12/24-500, BLW12/24-800, BLW24-10, BLW48-10, BLW48-400 depending on your needs.
