1.The module input IN- is forbidden to be shorted to the output OUT-.
2.Please ensure that the power of the power supply is greater than the power required by the output load!
3.If the module wants full load output, the input voltage should be 8V or more. When the input voltage is 5V, the output power is about 15W, and the voltage ammeter fails.The maximum current value of the module is 4A, which is limited by the maximum output power. For example, the output is 17V, and the current should be no more than 2A. This module has an output short circuit protection function. After short-circuit protection, the module automatically turns off the output, and the module can be restored after power-on.
