40 Amp 24 volt to 12 volt DC/DC Converters

800 Watt DC/DC 24 to 13.8 volt converter

This page: high power 24 volt to 12 volt DC/DC converters at low cost. 540 watts continuous.

These are fully regulated switching power converters (switchmode), designed to allow the use of 12 volt equipment in 24 volt vehicles. These are attractive, reliable, robust DC/DC converters good for fork lifts, off-road, construction and recreational equipment. This has "forced air cooling" and should be protected from water, spray, and dust that could be sucked into the power supply.
24 volt to 12VDC heavy duty DC/DC converters 5 Amp
More Heavy Duty, Consumer, Industrial, and Military Grade converters with 24VDC input

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

This has common ground, meaning that the input and output negative terminals are grounded together. This is applicable to most 12V requirements.
