  • How to choose an appropriate XINCOL DC24V-DC12V DC-DC Buck Converter with Memory Function? It usually depends on the wattage you want to power, e.g, for a 120W common device, you should go for 10A buck converter(12V×10A=120W), taking into account the overheat protection, which means the converter will break down if the inside temperature exceeds a certain degree after powering 12v device a long while which requires more power, if the wattage of powered device almost the same with 120W, we advise you choose buck converter with a power higher than 120W, such as 180W 240W or bigger, so that it can run much more smoothly.
  • The current of your powered device working for long time should not exceed the rated current of the buck converter
  • When wiring the converter wires, please try to make good insulation, which provides more safety.
  • It would be best for the buck converter being installed in a dry space with good ventilation and suitable temperature in order to avoid break down due to over-temperature protection.
