XD 24-12 Volt DC-DC Voltage Reducer

Xtreme-duty DC-DC Converter provides a 12 volt power source from a 24 volt system with a higher amp draw. Double battery 24 volt systems are superior in many ways to 12 volt models. Don't even think about converting the entire system to 12 volts. Also, it is not recommended to draw power from one battery only. Just use a converter to step down the voltage to power the 12 volt appliance. With the 24v-12v voltage reducer, you can run 12 volt auxiliary lights or other 12 volt units requiring up to a 25 amp (continuous) draw.

. "Thank you OKoffroad for your great customer service, competitive prices, and quality products! As a smaller fire department with limited funding, we are tasked to stretch our dollars without compromising quality of our equipment, operational safety of our personnel, while maintaining the best delivery of emergency services to our community. We are very pleased with the performance of the 24v-12v / 25 amp reducer and other accessories installed in our Federal Excess Property Program (FEPP) tactical tender (see attached pictures - sorry no mud!). We plan to continue use of this product as we bring additional FEPP units in-service. Again, thanks to you and your staff for a job well-done!"

"Here is our Military Hummer converted into a quick attack/brush fire vehicle. We used two of the 25 amp converters to run all of our strobe package and other vehicle lights that we upgraded as well as one solely dedicated to our radio and siren box."

24 volt System Info

24 volt electrical systems are found mostly in military vehicles such as Land Rovers, Pinzgauers, HummVees, and Unimogs. The system is made up of two standard 12 volt batteries. This differs from a dual battery system in a 12 volt truck, however. Instead of being connected in parallel, the two batteries are hooked up in series.

Parallel: Positives connected, and both negatives go to ground.

Series: Ground connected to negative terminal, positive connected to second negative, and second positive connected to all units.

Never run 12 volt accessories from one battery, especially a 12 volt unit that draws alot of power (winch, etc.). The danger is that power will be drawn from only one battery and the system will become unbalanced.

Some Do's & Dont's with 24 volt systems:
Do not draw power from only one battery for ANYTHING.
Swap around the batteries several times in the season.
Always charge both batteries fully.
Both batteries must be of the same type.

High efficiency vs. low efficiency converters:
Both high and low efficiency converters are available. Low efficiency converters are cheaper, larger and dissipate extra voltage by heat conversion. Units have large heat fins, and become quite hot. High efficiency converters are superior, run cooler, but are more expensive.
