CNC adjustment, precise and fast, step-down output, output voltage 0-50.00V arbitrary adjustment, limit current 0-20.00A arbitrary adjustment. Anti-reverse connection protection of 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 working parameters of the module exceed the protection threshold, the output is automatically turned off. Using synchronous rectification technology, the conversion efficiency is high, the efficiency is more than 90%. Increase heat sink, install fan, strengthen heat dissipation. Cautions: Module 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. Please ensure that the power of the power supply is always greater than the power required by the output load! This 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. The 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 time with high power! The module has input undervoltage 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 protection threshold, when the input current is relatively large , do not ignore the partial voltage on the input wire).
