24 Volt to 12 Volt Step Down

[countywacker]

Hi,

I have to install a 24v to 12v step down on a duce and a half. The truck is currently being used as a brush truck and we need to run the normal 12v items such as radio, siren and red emergency lights. I need a unit that has at least 5 connections.

I've looked around online and there is a ton of options. But is there converter that anyone favors before I purchase?

Let me amend my last post. I'm thinking of just running a connection from the voltage converter to a 6 position fuse block.


So I will not need a multiple connection converter. Just a single should work.

There are a multitude out there reasonably cheap. Just get one that will cover the amps and watts you need. Some folks add a second 12 volt alternator on as well. If you run off one battery keep it mind it WILL cause an imbalance eventually. Depends on your usage really.

Vanner makes 24 to 12 volt converters.

I have used Vanner and Newmar, both good units. First you should figure your current draw, then find one with a tad more capacity.I may have a spare Newmar, if interested PM me.

I tried PM'ing you and it said your box was full.

Cab you send me the info on the unit you have for sale.

I agree with "Gimpyrobb" and "Flyingvan911" about the "Vanner" unit. Our public transit fleet has used them for decades now. They work great !

How is it done with a 12 volt trailer... brakes and all? As far as creating an imbalance from working off only 1 battery, can you move your batteries around if one starts showing a little lower charge when full?

Thanks

If you use a "Vanner" it pulls power from both batteries for your 12 volt circuit, and feeds both batteries when charging.
