Feature:1. The controller can control the wind generator to automatically charge the battery. When the battery is fully charged, brake can be controlled automatically by the interior circuit. When the battery voltage declines to restore voltage level, wind can automatically restart the battery charging, so as to protect the wind and the battery.2. When charging, it has the function of limiting voltage and current to ensure the best charging effect. At the same time, it provides maximum protection for wind turbines and batteries.3. Unique reverse connect protection circuit. For improper operation the positive and negative of battery, don't need to replace the fuse, only to reset the positive and negative in correct point. So the whole system will be more reliable.4. The comprehensive waterproof protection. If the controller without waterproof but used in easy ooze water environment or the humidity is heavy, the controller is easy to be corroded and damaged. Our product adopts full seal completely waterproof design which adapt to the heavy humidity, salinity, such as ground water operational environment. The protection grade reaches the IP67 above, even in water it can steadily work normally for a long time.5. The product is made of aluminum alloy material, corrosion-resistant and has good quality.Spec:Condition:100% Brand New Item Type: Wind Turbine ControllerModel: FO4-12/24VMaterial: Aluminum AlloyApplicable Power: ≤400WVoltage: DC12-24VCurrent (A): 10-16Static Power Consumption Current: 8mAProtection Level: IP67Package List:1 x Wind Turbine Controller
