Fitting new converter

Hello. I have a '91 B-van with a 40 or 45 amp converter, which is now bad. (11 volts? Yeah, that's kinda low.) The current converter (a Magnetek 6300 series, I think) is on a tray with dimensions of 12" wide, 4.5" tall, and 7.5" deep.

I'd like to replace it with this, the 60 amp Intelli-Power model, but I'm seeing a problem: it won't fit. According to the site, the 60 amp Intelli-Power is 9" wide, 3.6" tall, and 8" deep - in short, a measly half inch too deep.

The Intelli-Power 45 amp model would fit, but there wouldn't be any air space above it. Is the lack of air space above it a problem? I'd really like to upgrade to a higher amperage model if I could, but if it's going to be significantly harder I'll consider the 45 amp.

My other thought was to mount the new unit on the floor somehow by the converter (it's under the couch, so it's still out of the way) and drill holes in the tray for the wiring. I can't easily ditch the tray or make major modifications to it because the cover panel bolts to the tray. I haven't investigated this in detail but finding room there shouldn't be a problem.

Anyone have any other suggestions? I'd like to stick with the Intelli-Power brand, because I've read a lot of good things about them.

I've never seen an Airstream like yours, so please take my comments with a grain of salt.

As a general rule, electrical devices require good ventilation so they can effectively dissipate the heat they generate while operating. So I'd be very wary of wedging a big converter into a small space. If you really want to try, you could call the converter's manufacturer to discuss your plans.

Changing the location of the converter (so it has ample air space around it) sounds like a promising idea. But again, I've never seen an Airstream like yours, so I can't say whether you'll run into other problems.

For what it's worth, I am currently moving the converter in my 2006 Safari 20 from its original location under the Fridge to a new location under the front bed. I'm sure this won't have any adverse consequences (and will in fact produce big benefits), because electrical current doesn't "know" where a device is located. In other words, as long as you use "hook up" wires of the proper size, you can mount the converter at a substantial distance from its original location.

Of course, there'll be a lot of little things to think about: making sure the converter is solidly attached, making sure all cables/wires are appropriately sized, making sure all cables/wires are well secured, so they won't pull loose or be damaged. And that's only the short list.

But after looking at your setup, if you feel you have plenty of room to reposition the converter...and if you're confident about choosing/connecting/securing proper cables, etc...then I'd go for it.

Hope these comments are helpful.

Regards,

Titus

Ah, I should've specified - the converter is mine is pretty much exactly the same as what's in any Airstream of that era, or at least the ones I've seen, with the possible exception that mine might be a lower amperage than trailers might have. Fortunately when Airstream built the B-vans they used quite a few off-the-shelf components.

So from that point of view, it's exactly like replacing one in a trailer or Class A motorhome.

Thanks.

Skater,
If you have the Magnetek 6300 series, the 60 Amp Inteli-Power converter you linked to WILL fit fine. The 45 will too but it's a very tight fit. We have thousands of the upgrades in service. There is also the Ultra III kit that is designed for the 6300 and we are even working on a Xantrex retrofit for it too. Let me know if I can help. There are several links on our site that show how to make the conversion.

Okay, thanks. I'll double-check what I have. I'd love to be able to pop the 60 amp model in there and be done with it.

D'oh. It's actually a 32 amp model, not a 40 or 45 amp!

It's a Magnetek 6332, 6300 A series.

That was the most popular. The 6325, 6332, or 6345 all are physically the same size.

Thanks!

Just wanted to update this: The new converter (60 amp) is installed and working well. Thanks for the help, 68 Overlander!
