LM2596 DC DC Step Down Converter Voltage Regulator LED Display Voltmeter 4.0~40 To 1.3-37V Buck Adapter Adjustable Power Supply

Touch the button to switch the measured input or output voltage, and there is an indicator to show which voltage is being measured, and save the setting, even if the power is turned on.

● The voltmeter can be closed, which can be easily achieved by tapping the left button when it is not needed.

● With terminal, no soldering iron can also be convenient to use, and retain the welding wire connection points.

● Input voltage 4.0~40V. (The input voltage must be 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)

● Output current 3A, recommended to use within 2.0A, large current needs to strengthen heat dissipation.

● Output power 20W, more than 15W, please strengthen heat dissipation.

● High conversion efficiency, with an average of 88% (efficiency is related to input and output voltage, current and pressure difference)

● With reverse connection protection, reverse connection does not burn

● With overheating protection and short circuit protection

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

● Weight: 22g
