Re: 24V to 12V Equalizer
That would be a good way to run 12v equipment on a 24v system without the problems of a center tap. It is kind of pricey though. The only 12v item left on my truck is a siren from its fire dept days which is kind of neat. It does not get enough run time to affect the batteries
