LM2596S digital display voltage regulator step-down power supply module

Model: YZQ-S017
Module performance and features:
1. With voltmeter display and self-calibration. Using a more advanced voltage microprocessor, the voltmeter error 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. The voltmeter can be turned off. When it is not needed, just touch the button on the left to easily achieve it.
3. With terminal blocks, it can be used easily without a soldering iron, and the soldering wire connection points are retained.
4. Input voltage 4.0~40V. (The input voltage must be higher than the output voltage by more than 1.5V) The adjustable output voltage range is 1.25V~37V and can be adjusted continuously. (The input voltage must be 1.5V higher than the output voltage)
5. The output current is 3A, it is recommended to use it within 2.0A, and large currents require enhanced heat dissipation. The output power is 20W, and please enhance heat dissipation when it exceeds 15W.
6. High conversion efficiency, averaging 88% (efficiency is related to input and output voltage, current, and voltage difference) with reverse connection protection, reverse connection will not burn
