These are fully regulated switchmode power converters, designed to allow the use of 24 volt equipment in 12 vehicles. These are attractive, reliable, robust DC/DC converters good for fork lifts, off-road, military, construction and recreational equipment. They are typically used for military equipment, PLCs, laser scanners, and wherever rugged 24VDC is required. They are ultra quiet, both in the input and noise fed back into the input.

To determine the amperage you need just add up the watts of all the equipment and divide by 24 volts.
These converters are fully isolated, and can be used for almost all 24 volt applications, grounded positive, negative, or ungrounded.
