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:

• 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
