24V to 12V Converter

A 24 volt to 12 volt converter steps a 24 volt supply down to 12 volts. That conversion is one of the most common in vehicles and industrial equipment, because 24 volts is the standard bus voltage of trucks, buses, industrial machinery, and many marine systems, while 12 volts is the voltage of the accessories those systems must run: lights, controllers, communications gear, and sensors. Without a converter, the two voltages cannot meet.

The buck category on this site lists a 24 volt to 12 volt option, and the isolated category lists a 35 to 100 volt to 12 volt option that also covers a 24 volt source at its lower end. The choice between a buck option and an isolated option turns on whether the load needs electrical separation from the source. A simple accessory load on the same vehicle usually does not, and a buck converter is the straightforward answer. A sensitive control board or a communications load may need the isolation, and the isolated detail page gives the fully specified option for that case.

Current is the figure that decides the size of the unit. A 24 to 12 volt converter must deliver the full current the 12 volt load draws, and the 24 volt source must supply a smaller current for the same power, since power is conserved across the conversion. A buyer specifying this conversion should state the 12 volt load current, not just the voltages, so the confirmation during the inquiry is based on the real load.
