LM2596 DC-DC adjustable step-down module with voltmeter display

LM2596 DC-DC adjustable step-down module with voltmeter display with voltage accuracy calibration

Module performance and characteristics:

●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.

●The voltmeter can be turned off, and it can be easily realized by touching the button on the left when it is not needed.

●With terminal blocks, it is easy to use without soldering iron, and the connection points of welding wires are reserved.

●The input voltage is 4.0~40V. (The input voltage must be more than 1.5v higher than the output voltage)

●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.

●The output power is 20W, please strengthen the 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 function

●Size 6.1*3.4*12cm (length*width*height)

●Weight: 22g

Application range:

This module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supply, 24V car pen meter power supply, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
