Buck Converter Step down XL4015 RED 5A / dc-dc Lithium Charger

This Buck converter can be used as a normal step-down module with overcurrent protection capability for various applications. It is used as a charger for various voltage lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs), for solar panels, wind turbines, etc.

This buck converter can also be used as a high power LED driver module.

The module comes with two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in.

Features

Short circuit protection: Yes(limited current 8A)

Over-temperature protection: Yes (automatically turn off the output after over temperature)

Input reverse connection protection: None, (If necessary, please input a large current diode in the input string)

Installation method: 4 3mm silk

Wiring method: terminal block or soldering terminal, V-IN is input.

Applications

use as a stepdown modules with overcurrent protection capabilities.

Usage:-

make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V or 2200mah, then the float voltage is 4.2V, the maximum charging current 1c, i.e. 2200ma) under no-load conditions, adjust the “voltage potentiometer” so that the output voltage reaches the float voltage.
