CB 24-12 Volt DC-DC Converter

This linear-designed Citizen Band (CB) DC-DC Converter is specifically designed for use with 12 volt CB radios only. Because CB radios are susceptible to noise interferences, this unit significantly reduces the potential of radio interference.

Is your vehicle ex-military with a 24 volt system? Double battery 24 volt systems are superior in many ways to 12 volt systems. Don't even think about converting the entire system to 12 volts. Also, it is not recommended to draw power from one battery only (see info below). Just use a converter to step down the voltage to power the 12 volt appliance.

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.
