Power step-down module, low ripple DC-DC converter, adjustable, convenient for overheat protection, good heat dissipation

Features:

1. This is a high efficiency 5A low ripple DC-DC step-down module and converts 4.0V~38V to 1.25V~36V.
2. The onboard voltmeter can be self-calibrated; using more advanced voltage microprocessor, the error of the voltmeter is ±0.05V, measuring range 0~40V
3. The input and output have screw terminals for convenient connection even without a soldering iron, and retain the solder pad for soldering connection
4. It supports overheating protection and short circuit protection function
5. Comes with heat sink for better heat dissipation, and several standoffs and nuts

Voltmeter Self-Calibration Instructions:
1.When the built-in voltmeter displays the output voltage, press and hold the right button for 2 seconds to enter output voltage regulation mode. The voltmeter display and output voltage indicator will flash synchronously.Similarly, when the built-in voltmeter displays the input voltage, press and hold the right button for 2 seconds to enter input voltage regulation mode. The voltmeter display and input voltage indicator will flash synchronously.br>2.Press the right button to increase the voltage value and Press the left button to reduce the voltage.Due to a voltage unit less than 0.1 V, you must press the button 1 to 5 times to see the voltage value.Changes by 0.1 V.
3.After setting the voltage, press and hold the right button for 2 seconds, then release to exit voltage calibration mode.All configured settings will be automatically saved in the event of a power failure.
Note: To ensure the voltmeter's accuracy, please ensure the input voltage is greater than 4.5 V.
