DC-DC step-down module:

Thickened circuit board:

Advanced Solid State Capacitors:

Short circuit and over temperature protection:

This module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V car pen power supplies, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.:

Module usage tutorial:

1. Input and output voltage measurement error calibration:

long press the switch for more than 4 seconds, and then enter the voltage measurement error calibration function after letting go.

At this time, the IN light is on (calibration input terminal), and the digital tube flashes to display the correct value (the factory parameter is 0.0).:

At this time, short press the button to change the value (the value range is -0.5 to 0.5, the unit is V). A positive number means upward calibration, and a negative number means downward calibration.:

After adjusting the calibration value of the input end, press and hold the button for more than 2 seconds, and then let go to the error calibration of the output end. At this time, the OUT light is on (calibrating the output end), and the calibration value of the output end is displayed. The adjustment method is the same as that of the input end. After the calibration value of the output terminal, press and hold the button for more than 2 seconds. After letting go, the set value will be saved and the voltage will return to normal display voltage. The set calibration value will take effect immediately and will not be lost after power failure. (With this function, you can meet your higher precision requirements):

2. Turn off the voltmeter:

Press and hold the switch for more than 1 second and less than 4 seconds, and release it to turn off. After the voltmeter is turned off, just short press the switch to turn on the voltmeter.

Precautions:

1. It is recommended that when the power usage exceeds 15W, it is necessary to add heat sinks to enhance heat dissipation;:

2. If the module output voltage cannot be adjusted, it is always equal to the input voltage. When you encounter this kind of problem, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally. Because this step-down module leaves the factory, the default output voltage is about 20V.:
