Multle software protection mechanisms are available, and the protection threshold is adjustable.When the working parameters of the module exceed the protection threshold, the output will be automatically closed. 1.7. Using synchronous rectification technology, the conversion efficiency is high: the efficiency is more than 90%. 1.8. Add heat sink Descrtion: Model:WZ5005L Display:LCD Input voltage range:6-55.00V; Input voltage resolution:0.01V Output voltage range:0-50.00V; Output voltage resolution:0.01V Output current range:0-5.000A; Output current resolution:0.001A Output power range:0-250.0W; Input voltage accuracy:±(1%+5) Output voltage accuracy:±(0.3%+5); Output current accuracy:±(0.5%+5) Typical value of output rple:150mV Peak value Normal operating temperature range:-10℃~40℃ Capacity measurement range:0-99.99AH Statistical error of capacity energy:±2% Statistical time range:0-100 hour Depreurization mode:differential preure >0.05%+1V Product size:79X43X42mm Soft start: Yes Protection mechanism: Input anti reverse connection; Input undervoltage protection (5.8-50v adjustable, default 5.8v) Output overvoltage protection (0-51.00v adjustable, default 51V) Output over-current protection (0-5.100a adjustable, default 5.1a) Output over power protection (0 - 260W adjustable, default 260W) Timeout protection (0 - 100h adjustable, off by default) Over capacity protection (0 – 99.99ah adjustable, off by default) Method of use 1. Switch display parameters -- in the normal interface, pre SW to switch the display below the display screen, and switch the display content between current A power W capacity Ah time h.Long pre SW on to switch the uplink display on the display screen and switch the display content between input voltage IN output voltage OUT. 2. Set output voltage -- pre U/I on in the normal interface to enter the interface of setting voltage constant current.It can be seen that a certain digit of the output voltage value is flashing. Rotate the left and right to adjust the major and minor.Short pre the rotary to choose which bit of output voltage to set.After setting, pre U/I on 2 times to return to the normal interface.Or automatically return to the normal interface after stopping operation for 10s. 3. Set constant current value (that is, the maximum current value allowed to output by the module) -- pre U/I on in the normal interface to enter the setting voltage constant current interface.Then pre U/I on and switch to setting constant current value. You can see a bit of the setting constant current value flashing. Rotate the rotary left and right to adjust the major and minor.Short pre the rotary to choose which bit to set the constant current value.After setting, pre U/I to exit the setting voltage constant current interface and return to the normal interface.Or automatically return to the normal interface after stopping operation for 10s. 4. Set the default on/off state of module power-on -- long pre U/I in the normal interface to enter the parameter setting interface.You can see that it shows "OPEN OFF" or "OPEN ON". "OPEN OFF" means the output is turned OFF by default when power is ON, and "OPEN ON" means the output is turned ON by default when power is ON.Long pre rotate to switch two states.After setting, long pre U/I to return to the normal interface. 5. Setting of protection parameters on state and threshold -- long pre U/I to enter the parameter setting interface in the normal interface.Pre SW until the protection you want appears.LUP -- undervoltage protection threshold;OUP -- overvoltage protection threshold;OCP -- overcurrent protection threshold;OPP -- over power protection threshold;OAP -- ultra-capacity protection threshold;OHP timeout protection threshold.Short pre rotate to select which bit you want to set the protection parameter.Long pre the rotary to set the protection parameters on or off (only timeout protection and supercapacity protection can be set to turn on/off, and other protection parameters are turned on by default.).Rotate the left and right to make the parameters bigger and smaller.After setting, long pre U/I to return to the normal interface. 6. Calibration voltage and current -- pre U/I on to enter the parameter setting interface under normal interface. Pre SW key for a short time until the interface with zero appears, with zero + out + a symbol. Pre and hold the rotary to complete zero calibration. Short pre SW on until a parameter interface with CAL appears.The calibration input voltage interface with the symbol CAL+IN+V;The calibration output voltage interface with the symbol CAL+OUT+V;The calibration output current interface with the symbol CAL+OUT+A.Rotate the left and right to adjust the size of parameters.After the adjustment is completed, long pre the rotary to confirm the adjustment is completed, and the parameter value is no longer flashing.Long pre U/I to return to the normal interface. Note: in order to ensure the accuracy of calibration, calibration voltage -- above 12V can only be started;Calibration current - start calibration only when the current is above 1A Cautions 1. Short connection between input IN and output OUT of the module is forbidden, or the constant current function will fail. 2. Please ensure that the power moment of the power supply exceeds the required power of the output load! 3. This module is a step-down module, the input voltage should be higher than the output voltage, and a certain margin should be reserved. For full load output, the input voltage should be 55v. 4. High power use of this module, serious heating, high temperature, be careful of scald! Please pay attention to ventilation and heat diation when using high power for a long time! 5. The module has input undervoltage protection function. The default value is about 5.8v (can be set). When the value is lower than this value, the output will be automatically disconnected (note that the voltage at the module port is lower than the undervoltage protection threshold. When the input current is relatively large, do not ignore the partial voltage on the input wire). Package included: 1 × DC 50V 5A Digital LCD Display Buck Power Supply Module
