36V 48V to 12V 40A 480W Step-Down Transformer DC to DC Buck Converter DIY Power Supply

[High-grade DC-DC Buck Converter] It uses premium quality electronic components and a waterproof (IP68) aluminum housing. Widely used for golf cart, club car, motor, speaker, GPS, car display screen, LED strip light, air-conditioner, electric fan, solar energy, DVD and other devices that require DC 12V voltage. [Input Voltage] DC 48V (Input
Range: 30V to 60V). A stable DC power is recommended as the input power supply, and the rated voltage supply should be within the voltage range of 30V to 60V. [Output Voltage] DC 12V (Output
Current: 40A). Please NOTE the output voltage/current/power is rated. [Multiple Protections] Built-in over-temperature, over-current, over-voltage, and output short-circuit protection to ensure your devices operate safely. [Easy to DIY] Connect INPUT wires to the power source and OUTPUT wires to your load device. The wiring diagram is labeled on the back of the buck converter. Please don't power on before completing the circuit and connection, and do not reverse the input and output interface. Two INPUT wires = Red wire (positive pole) + Black wire (negative pole). Two OUTPUT wires = White wire (positive pole) + Black wire (negative pole)
