1pcs x LM2596 LM2596S + LED Voltmeter DC-DC adjustable step-down buck converter

Input Voltage: 4.0 ~ 40V. (Input voltage must be higher than the output voltage of 1.5v or more)
Output voltage: 1.25V ~ 37V continuously adjustable.
Output current 3A, recommendations within 2.0A use, the high current needed to enhance heat dissipation.
Output power 20W, 15W, please enhance heat dissipation over.
High conversion efficiency, on average 88%
With reverse polarity protection
Size 6.1 * 3.4 * 12cm (L * W * H)
The input voltage should not exceed the maximum input voltage.
There could be a maximum output voltage difference of around 5%.
To ensure accuracy voltmeter, make sure the input voltage of 4.5V and above
