5A DC-DC adjustable step-down module XL4015 voltmeter 5 to 35V Efficiency
UK STOCK, UK SELLER
This is a really useful and simple to use general purposes voltage regulator, great for powering up your projects.
This module has a 180 KHz fixed frequency PWM buck (step-down) DC/DC
module,capable of driving upto a 5A load (with a suitable heatsink – NOT SUPPLIED) with high efficiency, low ripple and
excellent line and load regulation.The module has a digital voltage meter to
display the input voltage or output voltage, and the voltage can be
adjusted via the small screw on top of the potentiometer.

adjusted via the small screw on top of the potentiometer.
1) Pressing the left button switch the display on and off, it will NOT switch the output off
2) Pressing the right button will toggle the display to show the input voltage or output voltage.
3) To adjust the output voltage turn the small screw on top of the potentiometer. Anticlockwise decreases the output voltage and clockwise will incease the output voltage.
4) if the actual output voltage when measured with a multimeter, does not correcspond to the displayed output voltage on the module, then you will need to calibrate the module to represent the actual output voltage. This is achieved by the following procedure:-
a) Turn the display on by pressing the left button
b) Press the right button to display the output voltage
c) Press the right button again for 3 seconds and release, the display will flash, indicating you are in calibration mode
d) By repeatedly pressing the left button will decrease the display by 0.1 and
repeatedly pressing the right button will increase the display by 0.1. this procedure will NOT change the output voltage but is used to match the displayed output voltage with the actual measured output voltage. To save the calibration press right button for 3 secounds and release.
