V 8-36V to 12V 4A 48W Step-Down / Up Transformer DC to DC Buck Converter Golf Cart Power Supply

Versatile DC-DC Buck-Boost ConverterIt adopts premium quality electronic components and waterproof (IP68) flame-retardant ABS 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 requires DC 12V voltage. Input Voltage DC 8V to 36V. A stable DC power is recommended as the input power supply, and the rated voltage supply should be within the voltage range of 8V to 36V. Output VoltageDC 12V (Output
Current: 1A / 2A / 3A / 4A). Please NOTE the output voltage/current/power is rated. Multiple ProtectionsBuilt-in over-temperature, over-current, over-voltage, output short- circuit protection to ensure your devices safely. Easy to DIYConnect INPUT wires to power source, OUTPUT wires to your load device. The wiring diagram is labeled on the back of buck-boost. Please don't power on before completing the circuit and connection, do not reverse the input and output interface. Two INPUT wires = Red wire (positive pole) + Black wire (negative pole). Two OUTPUT wires = Yellow wire (positive pole) + Black wire (negative pole).
