Before powering on, check if the input and output leads are correct to avoid damaging the equipment and burning out the power supply2. The bottom component feet of the bare board power board can conduct electricity. During testing, do not touch the bottom of the board with your hands. It is necessary to place non-conductive materials such as insulating rubber pads or clean paper on the bottom of the board to avoid the risk of electric shock and burning the power board3. The AC-DC power module of this product is stable, constant voltage, and not constant current. Please confirm the voltage, current, and installation size you need before purchasingPackage include:Voltage reduction module * 1
