This fast charging module has voltage, current, power, display, powerful functions, Digital display of voltage, current and power, with separate fast charging indicator light, Using high-quality solid capacitors, double-wire large inductance, 3 screw positioning holes,The digital display shows voltage by default, and can be switched to current and power display by pressing the button.Output overcurrent, input overvoltage, input undervoltage, output short circuit protection Interface: Type-c+USB dual interface. Input voltage range: 6-35v, recommended within 33V. Output voltage range: 4V-20v, automatically adjusted according to the fast charging protocol. Support QC4+/QC4/QC3.0/QC2.0/FCP/AFC/SFCP/MTK/SCP/BC1.2/DCP. Output overcurrent, input overvoltage, input undervoltage, output short circuit protection. With digital display, the voltage, current and power can be switched by pressing the button soft start function. Output voltage line compensation function, line compensation voltage 50mV@1A. High current USB interface. 3 positioning holes of 3mm. Board size: 36x38x11.3MM. Instructions:The input voltage of DC interface or welding wire interface is 6-35V. It is recommended to be in the range of 12V-32V. The module is charged by step-down. If you want to output 12V voltage, the input must be greater than 12V, and the power supply must be sufficient. Use a high-current mobile phone charging cable to charge the mobile phone (the quality of the data cable will affect the charging speed). The power indicator light will be on when the welding wire is energized. The digital display shows voltage by default, and can be switched to current and power display by pressing the button. The first digit of the current mode displays "C", and the first digit of the power mode displays "P". Protocol introduction:; Support PPS/PD3.0/PD2.0; Support QC4+/QC4/QC3.0/QC2.0;
