These are fully regulated switching power converters (switchmode) with wide input voltage range, designed to provide regulated 13.8 volt power for equipment in 24 volt vehicles or 28 volt vehicles. These are attractive, reliable, robust DC/DC converters good for fork lifts, off-road, construction, military, marine and recreational equipment. They are ultra-quiet both electrically and acoustically.

To determine the amperage you need just add up the watts of all the equipment to be powered and divide by 13.8 volts.

These converters are common ground, or common negative, and will work in all vehicle applications with negative ground.
