Golf Cart 48V to 12V Converter DC Voltage Buck Reducer Transformer Voltage Regulator IP68 with Fuse for Yamaha Club Car EZGO (240W 20A)

Q: Im putting 47v DC in but have no power outA:Please check whether the power supply is reversed;Please confirm whether the fuse is not installed or damaged.Never connect to solar panel or wind turbine.Never charge the battery.Never reverse the polarity.Keep good air convection.High quality aluminum alloy shell package,good heat dissipation;Organic silica gel potting, IP68 grade, waterproof, dustproof, seismic resistance.Over-load, over-current,Over-temperature,output short-circuit protection;Pure copper wire inductance, effective filtering, oscillating, notching, ensuring the stability of the power supply.Red to bat+Black to bat - (next to red)Yellow to 12v loadBlack (next to yellow) to load GNDIts normal spark when you connect converter to battery.Its normal that case is hot and when its over 185?, the converter protects.When temperature is over 113?, touch the mental case and will feel very hot.For example, if max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads.If load device is motor or compressor, then you may choose 10A/0.5=20A according to real test result since motor and compressor starting current may be 2-3 times than nominal current.
