Feature 1 Automatic Charging: The controller can control the wind generator to charge the battery automatically. When the battery is fully charged, the wind generator is automatically controlled by the internal circuit to brake the wind generator. 2 Protection Capability: When the battery voltage drops to the recovery voltage, the wind generator resumes charging the battery, thus protecting the wind generator and the battery. 3 Modular Design: The rectifier and brake circuit part of this controller is designed with an integrated module, which is further than the traditional design in terms of heat dissipation and reliability. 4 Comprehensive Waterproof Protection: The controller adopts a fully sealed and completely waterproof design, with a protection level of IP67 or above, which can be applied normally for a long term even if it is placed in water, and its stability and reliability are greatly improved. 5 Aluminum Alloy Housing: The controller adopts aluminum alloy housing with multi edge base plate design to increase the heat dissipation area. It can make the controller keep in the best heat dissipation state for a long term.Item Type: Wind Generator ControllerMaterial: Aluminum alloyRated Battery Voltage: 48V Rated Wind Generator Capacity: 400W Wind Generator Braking Voltage: 60V Wind Generator Recovery Voltage: 54V IP Protection Grade: IP67 Package List1 x Wind Generator ControllerNotePay attention to the security of electricity, wiring to be accurate.
