Precautions a. This buck converter does not have reverse connection protection. Always verify the correct polarity of both the power source and the load before wiring to prevent damage from reverse polarity. b. Ensure the input source provides sufficient voltage and power to operate the connected device. c. The voltage requirement of the connected device must match the output voltage of the converter. The power draw of the load must not exceed the maximum rated output power of the converter.
