If your rig runs a 24V electrical system and the accessory you want to fit is 12V, this is the part that bridges the two. 30 amps of 12V output from a 24V supply — enough for a fridge, a run of lights and a couple of USB outlets together.

One thing to be clear about, because it is the most common mix-up in this category: this is a converter, not a DC-DC battery charger. It takes 24V in and gives steady 12V out to run equipment. It will not charge a second battery from your alternator — that is a different device with a charge profile in it. If you are after alternator charging for a house battery, this is not the part you want.
