LM2596 2A Buck Step down Power Converter Module DC 4 ~ 40 to 1.3 37V LED Voltmeter

LM2596 2A DC 4-40V TO 1.3-37V Buck LED Display

Presenting the LM2596 2A DC 4-40V TO 1.3-37V Buck LED Display Module, designed to convert DC 4 ~ 40V to 1.3 ~ 37V with ease. Equipped with a built-in voltmeter display and powered by an advanced microcontroller.

Alongside its precise multi-turn potentiometer, this allows for easy adjustment of the output voltage within the supply range, without requiring an external voltage meter. LM2596 2A DC 4-40V TO 1.3-37V Buck LED Display also offers a vast operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.

Steps for calibrating the output voltage:

• First, adjust the right button until the “OUT” LED is illuminated and the voltmeter displays the output voltage. Then, hold down the right button for at least 2 seconds and release it. This will cause both the voltmeter and “OUT” LED to flash simultaneously, indicating that you have entered the output voltage calibration mode.
• In Step 2, you can adjust the voltage value by pressing the right button for a unit increase at normal speed or the left button for a unit decrease. Keep in mind that the minimum display increment is 0.1V, so you may need to press the button 1-5 times in succession to see a change of 0.1V on the voltmeter. The number of presses required depends on the current displayed voltage; with higher voltages, fewer presses will be needed.
• To complete Step 3, simply hold the right button for over 2 seconds, then let go to exit the output voltage calibration mode. This will automatically set all parameters to power down and save.

Steps for calibrating input voltage:

• Step 1: Adjust the right button until the “IN” LED is lit and the voltmeter displays the input voltage. Hold down the right button for at least 2 seconds, then release. The voltmeter and “IN” LED will flash together, indicating that you are now in input voltage calibration mode.
• Following the same method for calibrating the output voltage, we proceed with steps 2 and 3.
• The paragraph has already been written to avoid repetition. The following is a possible rephrasing:
• The maximum current that the LM2596 can handle is influenced by various factors, such as the input and output voltages, ambient temperature, and cooling. In order to meet these maximum ratings, it may be necessary to use an external heatsink. However, it is important to note that the operating temperature of the LM2596 should not exceed 125°C. Going above this temperature could result in permanent thermal damage.

Characteristics of LM2596 2A DC 4-40V TO 1.3-37V Buck LED Display:

• Ensure that reverse polarity protection is included in the input.
• The built-in function that protects against short circuit.
• The integrated thermal shutdown feature
• Push the correct key to display the input or output voltage. When the “OUT” LED is illuminated, it indicates output, while the “IN” LED displays input.
• The power-off memory function displays the most recent measured voltage values for the road after a power outage.
• To deactivate the LED display, press and hold the touch button for 3 seconds. Simply touch the button once more to reactivate the display.
• The terminals of the band, besides being user-friendly, also provide a secure connection point for wires.
