LM2596 DC-DC Adjustable Step-Down Module With Voltmeter

With voltmeter display and the voltmeter can be self-calibrated. It adopts a more advanced voltage microprocessor, the error of the voltmeter is ±0.05V, and the range is 0~40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)
Touch the button to switch between measuring input or output voltage, and there is an indicator light to show which voltage is being measured, and the setting is saved, even if the power is turned off and on again.
Adjustable output voltage range 1.25V~37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
The output current is 3A, and it is recommended to use it within 2.0A. The high current needs to strengthen the heat dissipation.
Comfortable price, intelligent and user-friendly design, and cost-effective!

Large currents need to strengthen heat dissipation.
The output power is 20W, please strengthen heat dissipation if it exceeds 15W.
High conversion efficiency, an average of 88% (efficiency is related to input, output voltage, current, and pressure difference)
With reverse connection protection, reverse connection will not burn
With overheating protection and short circuit protection
