Upgraded X16009 Dc-Dc Adjustable Boost Module 5-32V to 5-40V 4A with Digital Display Volt-meter

Product Details:Adjustable step-down module with voltmeter LM2596 

Module performance and characteristics:
1.With voltmeter display and the voltmeter can be self-calibrated. Using 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)
2.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.
3.The voltmeter can be turned off, and it can be easily realized by touching the button on the left when it is not needed.
4.With terminal blocks, it is convenient to use without soldering iron, and the connection points of welding wires are reserved.
5.Input voltage 4.0~40V. (The input voltage must be more than 1.5v higher than the output voltage)
6.Adjustable output voltage range 1.25V~37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
7.The output current is 3A, and it is recommended to use it within 2.0A. Large currents need to strengthen heat dissipation.
8The output power is 20W, please strengthen heat dissipation if it exceeds 15W.
9.High conversion efficiency, an average of 88% (efficiency is related to input, output voltage, current, and pressure difference)
