This is a 20W adjustable DC-DC buck converter module with digital display. It is based on LM2596 3A step-down voltage regulator and supports an input of 4~40V DC with an accuracy of ± 0.05V.

On a regular buck converter there is no display and you have to measure the output manually with a multimeter, which can be slow and inefficient. This buck converter has a display with the output voltage readout integrated right in to the board. You can change the output by adjusting a screw potentiometer that is also integrated on to the board. Simple!

This module can be used in DC applications such as batteries, power transformers, DIY adjustable power supplies, 24V vehicle power supplies, industrial equipment, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and so on.

Tapping the button switches between input and output voltage measurement. Hold the button for 2 seconds and release it to disable the display.

Note: The adjustment knobs are 30-turn potentiometers that control the voltage and current limits. This means you may have to turn them up to 30 turns to get from the top of the output limit range (36V) to your target voltage.

Features:

  • Touch the button to switch the measurement input or output voltage, and an indicator shows which voltage is being measured.
  • The display can be disabled if necessary. Hold the button for 2 seconds, and release the button to turn off the display (output will remain on).
  • With wire terminals, no soldering is necessary
  • The input voltage is 4.0 ~ 40V. (The input voltage must be 1.5V higher than the output voltage)
  • Continuously adjustable output voltage range of 1.25V ~ 37V. (The input voltage must be 1.5V higher than the output voltage)
  • The Maximum output current is 3A, it is recommended to use within 2.0A, higher currents will need a heatsink to dissipate heat.
  • The output power is 20W. For more than 15W a heatsink is recommended.
  • The unit offers high conversion efficiency, with an average of 88%
  • The unit includes reverse polarity protection, overheating protection, and short circuit protection
