["brand new and high quality\nFeatures:\nLCD can display input/output voltage, output current/output power/output capacity/output for time.\nCNC adjustment, precise and fast, step-down output, output voltage 0-50.00V arbitrary adjustment, limit current 0-20.00A arbitrary adjustment.\nAnti-reverse connection for protection of input end, which will not burn out.\nThe module can be set to open/close by default.\nMultiple software for protection mechanisms are available, and the for protection threshold is adjustable. When the working parameters of the module exceed the for protection threshold, the output is automatically turned off.\nUsing synchronous rectification technology, the conversion efficiency is high, the efficiency is more than 90%.\nIncrease heat sink, install fan, strengthen heat dissipation.\n\nCautions:\nModule input positive electrode IN+ and negative electrode IN- are forbidden to connect inversely, short connection between input IN- and output OUT- of the module is forbidden, otherwise the module may burn out.\nPlease ensure that the power of the power supply is for always greater than the power required by the output load!\nThis module is a step-down module, the input voltage is higher than the output voltage, and a certain margin is left. If you want to output at full load, the input voltage should be above 55V.\nThe high power use of this module is very hot, high temperature. Be careful of scald! Please pay attention to ventilation and heat dissipation when using for a long for time with high power!\nThe module has input undervoltage for protection function, the default is about 5.8V (can be set), when below this value, it will automatically disconnect the output (note that the voltage at the module port is lower than the undervoltage for protection threshold, when the input current is relatively large , do not ignore the partial voltage on the input wire).\n\nSpecifications:\nDisplay: LCD display\nInput voltage range: 6-55.00V\nInput voltage resolution: 0.01V\nOutput voltage range: 0-50.00V\nOutput voltage resolution: 0.01V\nOutput current range: 0-20.00A\nOutput current resolution: 0.01A\nOutput power range: 0-1000W\nInput voltage accuracy: ±(1%+5 digits)\nOutput voltage accuracy: ±(0.3%+5 digits)\nOutput current accuracy: ±(0.5%+5 digits)\nTypical output ripple: 150mV peak-to-peak\nCapacity measurement range: 0-999.9AH\nStatistical error of capacity energy: ±2%\nStatistical for time range: 0-100 hours\nStep-down working mode: differential pressure>0.05%+1V\nSoft start: yes\nfor Protection mechanism: Yes\nInput undervoltage for protection (5.8-50V adjustable, default 5.8V)\nOutput overvoltage for protection (0-51.00V adjustable, default 51V)\nOutput overcurrent for protection (0-20.10A adjustable, default 20.10A)\nTime-out for protection (adjustable from 0-100h, closed by default)\nOver-capacity for protection (0-999.9Ah adjustable, closed by default)\nMaterial: ABS\nPanel Size: app.79x43x42mm/3.11x1.69x1.65in\nColor: As pictures shown\nQuantity: 1set\n\nNote:\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x Panel\n1 x Motherboard\n2 x Connection Lines(other accessories demo in the picture is not included.)"]
