Description

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 0~40V 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 into the board. You can change the output by adjusting a screw potentiometer that is also integrated onto the board. Simple!

 

 

The onboard voltage meter supports self-calibration mode. You only need to calibrate it once and the value will be stored automatically. The method is as follows: 1. Hold the button for 3 seconds. Release the button to enter input voltage calibration mode (“IN”is ON) ; Hold the button for 3 seconds and release the button to enter output voltage calibration mode (“OUT” is ON); hold the button for 3 seconds, and release the button to exit calibration mode, all parameters will be saved automatically. 2. In the calibration mode, click the button to adjust the value.

  • Supports self-calibration function to provide a high-precision voltage output. (Recommended input voltage is maintained at 4.5V or more)
  • 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
  • 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
