Feature 1 This controller can control wind turbines to charge the battery automatically .When the battery is fully charged, brake can be controlled automatically by the interior circuit. 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 Voltage and current limiting are be enabled during recharging to ensure the best charging effect. Meanwhile, it provides the maximum protection for the wind turbine and battery. 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, then the controller is easy to be corroded and damaged. Our product adopts full seal 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 can steadily work normally for a long time. 5 It is made of aluminum alloy material, which is corrosion-resistant and has good quality.Condition:100% Brand New Item Type: Wind Turbine ControllerModel: FO5-12/24VMaterial: Aluminum AlloyApplicable Power: 500WVoltage: DC12-24vProtection Level: IP67 Package List1 x Wind Turbine Controller
