Features 1、Operating Principle: The controller can control the wind turbine to automatically charge the battery. When the battery is fully charged, the fan will be braked automatically by the internal circuit. When the battery voltage drops to the recovery voltage, the fan will resume charging the battery. 2、Modular Design: The modular design maximizes the performance of the controller. No matter in terms of heat dissipation or reliability, it is better than the traditional design. 3、Waterproof Performance: This controller adopts a fully sealed and completely waterproof design, and the protection level has reached IP67 or above. Even if it is placed in water, it can be used normally. 4、Best Heat Dissipation State: The aluminum alloy shell and the multi edge bottom plate design increase the heat dissipation area. It can keep the controller in the best cooling state for a long time. 5、Ideal Replacement: This controller with excellent waterproof and protective performance, can be easily installed, ideal replacement for the old and damaged parts.
