Default Need to replace 30 year old converter

Hi all

It is looking like the old converter in my 1990 VanAmara is not putting out 12v. I will do a bunch of troubleshooting tomorrow, but given its age, I think it has probably given up the ghost.

The van is very simple, 3 way fridge, furnace and a smattering of interior lights. No a/c... The current unit is by a company no longer in business, and is a simple all in one unit. The only 110v in the vehicle is actually part of the unit, and it has separate output for the batteries and 12v accessories. It is only a 20 amp unit, as there really isn't much to draw power. I would up the amp's, but 40-50 would be ample.

I have attached a photo of the data plate of the existing unit that shows the details.

I have been hunting, but I am not really seeing anything that is basic, but offers a 110 outlet as well.

Any suggestions??

Thanks
Scott

What you have is a vintage converter + battery charger. Typically they have a 12 volt distribution panel with fuses, some 120VAC breakers and a battery charger. I think this manufacturer is out of business.

Even if you could get the unit working, it is pretty much out of date having been replaced by 3 stage smart chargers with charging capacity well above the 5 amps this one provided.

I suggest you record the physical dimensions of the unit, expose the innards as much as practical, take some photos and contact the go-to guy for this category of equipment who is Randy at Best Converter. He may be able to supply a drop in replacement that is cost effective, easy to install and will more than repay itself by significantly lengthening your battery life.

If upgrading to a higher output unit then thoroughly inspect the entire run of DC wiring to the battery(ies). You will likely find that the wiring will be undersized for the 40 to 50 amp units you mentioned. 6 ga wire would be rated to handle 50A DC. The wire gauge (size) should be stamped on the wire insulation.

Thanks for the information, much appreciated. I did get it back up and running, simply a blown fuse inside the unit. I have sent an email to Best Converter to see what the have.

Thanks again
