Item features:Product Name: Fan Boost ControllerProtection class: IP67Static order number: 15mAApplicable battery: lead acid/colloidSystem voltage: DC12V/24V/48VWorking temperature: -35~70Start voltage: 6V/12V/24VShell material: aluminium profileMaximum power: 12V300W/24V600W/48V800WPlease wire in the following order, pay attention to plus and minus pole1.Connect the battery, the controller automatically detects the system voltage (the controller can work with a system voltage of 12 VDC, 24 VDC and 48 VDC). From left to right, the fourth red wire is connected to the positive electrode of the battery, and the fifth black wire is connected to the negative electrode of the battery.2.Connect the wind turbine.The three green wires on the left side are connected to the fan generatorStatus display: LED display, Display content, Status, FunctionGreen LED: Fan charge indicatorAlways off: The fan is not connected or there is no wind blowingNormal high: Fan charge stateRed LED: fan brake indicatorAlways off: The controller works normallyContinuous light: overvoltage or over temperature protection of the dense batteryProperties:1.With aluminum profile heat dissipation housing, excellent heat dissipation properties, IP67 protection class2.With overcharge protection, electronic short circuit protection.The built-in temperature switch allows the controller to provide over-temperature protection.3.Various status indicators, easy to understand current working status of the system.The wind generator has a boost charging function and the wind is charged.Safety precautions:No. 1 Do not immerse the control unit in corrosive liquids, it will damage the control unit and produce harmful gases.No.2 When connecting the system, the voltage may exceed the safety voltage of the human body. When operating, be sure to use insulating tools and keep your hands dry.No. 3 In the 12/24/48 VDC system, the internal fuse of the controller is damaged if the battery terminals are incorrectly connected.No.4 The battery stores a lot of energy, so avoid a short circuit of the battery under all circumstances. It is recommended to put a fuse in series for short circuit protection.No. 5 can produce flammable gas, please stay away from sparks.Scope of delivery:1*Wind generator controller Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-dadangjia
