XL4015 5A Variable Voltage & Current Step Down Power Module with DUAL LED Display

The XL4015 5A Variable Voltage & Current Step Down Power Module with LED Display is a small module that has an integrated display that allows you to modify the output voltage and current limit. This little DC-DC module is a voltage step-down (buck) converter module that is based on the XL4015 and has an adjustable current limiter in addition to a daughterboard that shows the output voltage and current. This enables it to be easily used for a variety of purposes, including battery charging, LED driving at a steady current, and functioning as a compact, adjustable power source with current limitation.

The module has an output voltage range of 0.8V to 29V at up to 5A and an input range of 5V to 30V. The module operates at a fairly comfortable 1.5A, and unless some air flow is supplied via the module to assist keep things cool, it should only be used at 3A.

Features:

1. Built-in display of output voltage and current
2. Output voltage adjustment and Output current limit adjustment
3. Output current up to 5A with cooling and 3A without cooling
4. Input voltage range 5 to 30V and Output voltage range 0.8 to 29V
5. High efficiency: The module uses chips with high efficiency up to 95%, and can go to 5A current.
6. The voltage difference between input and output is 1V, with a minimum output voltage of 0.8v.
7. This module is an adjustable step-down module. The output voltage can be changed by adjusting the blue adjustable resistor on the module.
8. The module above marked IN-(input negative), IN+(input positive), OUT-(output negative), and OUT+(output positive) must be correctly connected, otherwise, it may lead to module damage.
