36V/48V Auto-shift 20A Solar Controller for Traffic Light/Solar Road Light Regulator/Solar Battery Emergency Exit | Обустройство дома

36V/48V Auto-shift 20A Solar Controller for Solar Traffic Light/Solar Road Light Regulator/Solar Battery Emergency Exit Light 1. Equipped with the MCU, artifically controlled,36V/48V automatic identification system voltage 2. Equipped with device to avoid the overcharge, over release, electronic short circuit, over loading, battery inversely connecting, solar battery inversely connecting.3. Use the battery discharge rate characteristics to correct discharge control.4.The series connection PWM circuit is implemented to form the major charging circuit,make the voltage loss half of or lower than the diode charging circuit,and the charging efficiency 3%-6% higher than the non-PWM.5. The LED shows the batteries current situation to make the customer get the information of the batteries.6. Three operating modes can be selected: normally open mode, the pure light control mode and light control plus timing mode.  1:The batteries has stored much energy,please keep the batteries from the         short circuit under any circumstances,we strongly recommend connecting the batteries with the fuse.            2:Please avoid the short circuit wire and the terminal,for the wire and theterminal may generate voltage two times higher than the rated voltage of the controller.Please use the insulated tools while operating the controller.3:Ensure the children keep away from the battery and the controller.4:Please comply with the manufacturer`s safety advice.5:Because of the equipment work may have a fever, please keep ventilation.6:The device pay attention to water,moisture,in order to avoid damage to the equipment. The controller is only applicable to solar power, rated voltage of 36V or 48V systems, battery of gel batteries, liquid openings or sealed lead-acid batteries.Note: specifically how much battery charge, see the product model, product can not be adapted to the various systems.  Charging mode:                                           PWM ModeSystem Current:                                          20ASystem Voltage:                                          36/48V AutoWithstand volatage input:                           less than 100VRated voltage load current:                        ≤11.5mA @36V, ≤12.5mA @24VOverpressure protection voltage:               49.5V±1.5% @12V, 33.0V±1.5% @24VOverpressure recovery voltage:                15.0V±1.5% @36V, 66.0V±1.5% @48VOver-discharge prptection voltage:            48.0V±1.5% @36V, 60.0V±1.5% @48VOver-discharge recovery voltage:              43.4V±1.5% @36V, 43.2V±1.5% @48VEnhance charge voltage:                           44.4V±1.5% @36V(1H), 59.2V±1.5% @48V(1H)Equalizing charge voltage:                         43.2V±1.5% @36V(1H), 57.6V±1.5% @48V(1H)Floating charge voltage:                             41.4V±1.5% @36V, 55.2V±1.5% @48VCharge return voltage:                               39.6V±1.5% @36V, 52.8V±1.5% @48VTemperature compensation:                       -30mV/℃/12VWorking temperature:                                 -30 ℃--+55 ℃Storage temperature:                                 -45 ℃--+70 ℃Humidity Requirement:                               ≤90 RH,no condensationProtection degree:                                      IP30Outside dimensions:                                  120*76*38mmAssembly line Size:                                     AWG22-10/5Square centimeter
