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.
Features:
Supports self-calibration function to provide 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
