This is an XL4005 based DC step-down/buck converter module with voltmeter and ammeter display It can be used as a battery charging module, LED driver or a general power supply. It accepts any voltage from 5V to 30V on the input and bring it down to 29V - 0.8V on the output terminal. The input voltage must be higher than the output voltage.
This module can output in constant current and constant voltage mode. It has digital display for each parameter to make read-out more convenient. Output current and voltage adjustment can be made using the two precision potentiometer.
Pay attention to the polarity on the board when making connection. Reverse polarity might burn the module.
Features:
A step-down/buck converter that uses XL4005 as the main control chip
Adjustable output current and output voltage
Digital display - 0.28" easy read-out display for output current and voltage
Three LED status indicator - Constant Voltage, Constant Current and input power
Small and compact size
Technical details:
Input voltage: 5V - 30V (input voltage must be higher than the intended output voltage)
