& OOTDTY Features: LCD can display input/output voltage, output current/output power/output power/output time. CNC adjustment, precise and fast, step-down output, output voltage 0-50.00V arbitrary adjustment, limit current 0-12.00A arbitrary adjustment. Protection against reverse connection of the input end, which will not burn out. The module can be set to open/close by default. Multiple software protection mechanisms are available, and the protection threshold is adjustable. When the module's operating parameters exceed the protection threshold, the output is automatically disabled. Using synchronous rectification technology, the conversion efficiency is high, the efficiency is more than 90%. Increase heat sink, install fan, strengthen heat dissipation. Remarks:The module's input positive electrode IN+ and negative electrode IN-are prohibited to connect backwards, the short connection between the input and output of the module is prohibited, otherwise the module may burn out. Make sure that the power supply is always greater than the power required by the output load! This module is an input voltage step-down module, the input voltage is higher than the output voltage, and some margin remains. If you want to output at full load, the input voltage should be above 55V. The high power of this module is very hot, high temperature. Watch out for burns! Please pay attention to ventilation and heat dissipation when using for a long time with high power! The module has input undervoltage protection function, the default is about 5.8V (can be set), when it is below this value, it will automatically disconnect the output (please note that the module port voltage is lower than the undervoltage protection threshold when the input current is relatively large, Do not ignore the partial voltage of the input wire).
