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.

Notes: Maximum current is dependent on input and output voltages, ambient temperature and cooling. To achieve maximum ratings an external heatsink may be required. Maximum LM2596 operating temperature must not exceed 125°C otherwise permanent thermal damage can occur.

Features :

  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

    I am satisfied with the products and its cheaper. It work perfect in my 3D printer, which I converted to Laser Printer as well. I have no other comments to make other than Fedex delivery which took a week.


  5. Vivek (verified owner)

    Good product. Works well.
    But they should avoid sending by Fedex. Fedex took one week for deliver from the shipping date. They made fake entry without delivery for 2 days in Chennai. After my complain only they deliver the parcel.


  6. bennur.praveen (verified owner)

    Works perfectly with direct input from my Solar panel(12v 50w). Doesnt get heated even after 5+ hrs of continuous usage,but with onset of summer and temperature shooting more than 40 in march-april it will be its real test.


  7. ganeshniranj (verified owner)

    Works as specified


  8. Manojit Majumder (verified owner)

    its works really well with my 12v lead acid battery .
