20 Amp 24 volt to 12 volt DC/DC Converters

40 amp peak DC/DC converter, 24VDC to 13.8VDC
24 volt to 12VDC heavy duty DC/DC converters 5 Amp
More Heavy Duty, Consumer, Industrial, and Military Grade 24VDC to 12VDC Converters

This page: high power 24 volt to 12 volt DC/DC converters at low cost. 400 watts peak, 270 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. Those that are listed as "forced air cooling" should be protected from water, spray, and dust that could be sucked into the power supply.

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

These are also known as 24 volt voltage reducers, and voltage regulators. These DC/DC voltage reducing converters are suitable for running electronics, such as radios, CD players, computers, and CB radios. They are can be suitable for motors, solenoids, or other electromechanical devices if they are protected from inductive kickback and motor noise, and the converter's output current is rated for the inrush, stall, and locked rotor current of the load.
