Specifications: Input voltage: 12-24V (DC) Output: DC5V/4A 9/2.5A 12V/2A 15V/1.6A USB+TYPE-C output: 5V/4A Output power: 20W PCB size: 44.5MM (long) * 22MM (width) * 24.5MM (high) Instructions for use: 1 When using, please insert PDQC3.0QC2.0FCPAFC to cooperate with the device, the module will automatically recognize the output suitable for charging mode (the output port has TYPE-C port and USB port for selection) USB port: 12-24V, QC/2.0/QC3.0: 5V/4A, 9V/2.5A, 12V/2A 12-24V, AFC: 5V/4A, 9V/2.5A TYPE-C port 12-24V QC/2.0/QC3.0: 5V/4A, 9V/2.5A, 12V/2A 12-24 PD: 5V/4A, 9V/2.5A, 12V/2A 24V PD: 15V1.6A 12-24V AFC: 5V/4A, 9V/2.5A 12-24V FCP: 5V/4A, 9V/2.5A 2. When using dual port simultaneous output, the voltage of the two output ports will be adjusted to 5V (the total current is 4A) NOTE: 1. The input voltage should not be higher than 30V, and the wiring should be correct (red is connected to the positive pole of the power supply and black is connected to the negative pole of the power supply) 2, because there is no outer casing, you can not touch the inductor and IC chip by hand when charging, in case of hot 3. When charging, keep the module clean and the bottom pad is insulated to prevent short circuit. 4. When the module is overcurrent protected, the module will restart continuously. Please disconnect the charging device and the module will return to normal. When the module is overheated, the module will stop working. When the temperature drops by 30 degrees, the module will resume normal operation.
