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

Product Details

QUICK OVERVIEW

1. Input Voltage(VDC): 4 ~ 40.
2. Output Voltage(VDC): 1.3 ~ 37.
3. Output Current: 2A Rated, ( 3A maximum with heat sink).
4. Switching Frequency: 150 kHz.

6. Built-in output short protection function.

This is LM2596 2A Buck Step-down Power Converter Module DC 4 ~ 40 to 1.3 ~ 37V, it comes with a built-in voltmeter display and uses an advanced microcontroller.

Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.

Output voltage calibration steps:

Step 1: Adjust the right button so that “OUT” LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and “OUT” LED flashes in synchronization so that you enter the output voltage calibration mode.

Step 2: Press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.

Step 3: Press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.

Step 1: Adjust the right button so that “IN” LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, release, voltmeter and “IN” LED flashes in synchronization so that you enter the input voltage calibration mode.

Steps 2 and 3, consistent with the output voltage calibration method.

1. Input reverse polarity protection
2. Built-in output short protection function
3. The built-in thermal shutdown function
4. Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input.
5. Power-off memory function, show that road after power voltage values measured for the last time
6. Press the touch button for 3 seconds to turn off the LED display, touch the button again to turn on the LED display
7. The band terminals, no iron can also be easy to use, and retention wire connection point

1 x LM2596 2A Buck Step-down Power Converter Module.
