I just jumped into this forum. We have a 2007 25' International CCD, and I want to upgrade the converter to get rid of the hummmmmmmm. I'm looking through the web at the Intellipower converters. Does anyone know which model is a direct replacement for the factory installed unit? Our rig is stored two hours away, and I want to order a new converter for when I next get to use our AS.

Thanks,
David

David,

Call Randy at Best Converter, I went with his recommendation, (see post 13). Great unit!

Like Robert said, give BestConverter a call, but honestly pretty much any of them will work. I was able to fit an Intellipower 9260 in the old style Magnetek case without an issue, and fitting another 9260 in the new trailer was even easier - it was smaller than the original converter.

Please help.
I just installed a new Progressive Dynamics 9260: 60 Amp Converter and new fuse box in my 1977 Argosy. After installation, a 5 amp GFCI Circuit breaker in the 120v barker box keeps tripping. Lights and outlets still work, but whatever the 5 Amp Circuit breaker controls does not.

A 5 amp GFCI? If so that's your problem. Use a 15 amp breaker to supply power to a receptacle then just plug the new converter into it.

GFCI is Tired

77Argosy,
I replaced my univolt with an intelipower 9260 just like yours a few months back. Check this thread and you can see the issues I had. http://www.airforums.com/forums/f449...ion-78743.html Bottom line though was I just needed to replace the GFCI circuit breaker. They get old, just like everything else and it would seem that they are fine when everything sending power thru it is also old, when you put in that new converter, it just cannot keep up.
Either way, I hope this is a simple fix for you and I think it will be. (And you may have misread the breaker, it is probably a 15, not a 5) When you go to buy the breaker, make sure you know what kind/brand of breaker panel you have. I was a bit naive when I walked into the store. One size does not fit all. luckily I had taken a picture with my phone earlier and was able to show the clerk that it was a GE box.
Good luck !

I'm puzzled about something here. . . the old copper-and-iron boat anchor converters were notorious for their hum, but does your 2007 model have one of those? I would think that Airstream has been putting high-frequency switching converters in their trailers since at least 2000, and I have never heard of any of those "humming".

We replaced the iron converter in our 1980 trailer with an Intellipower around 2007 and as far as my ears can hear (not very well) it's silent.

Unintellipower

I replaced the guts off my Univolt with a 9245. I cut off the back half of the Univolt gutted it except for the fuse panel and mounted the Intellipower on the old Univolt chassis. The only problem I have had with the old fuse panel in at least 5 years is you can't find those 40 amp AGM fuses. But you can replace the fuse with a 40 amp thermal break, clips right in.

I wonder if Sparkygus has a particularly loud fan on his? Mine is essentially silent also until the thermostat turns the fan on. I've noticed that when the sun warms up that side of the trailer the fan comes on and is noticeable, particularly when nothing else is on (even when batteries are in storage mode). Mine is located in a small cubbyhole below the pull out pantry and I think I can find a better way to ventilate that space so it stays cooler.

I read the ubiquitous Univolt humm is from breakdown of the varnish on the armature. Theoretically the armature can be repotted and the humm stopped. Or so I have been told.

On the way to buy a new 15 Amp GF breaker.
This is what the install looks like...Note, we clean dry and put flooring on the wood decking.

That looks very nice. I have batteries in a storage box on the front forks, intellipower up front, inside on the floor, fuse box is mounted on the wall just above it, and the breaker box is all the way in the back, under the sink. Having it all in one spot looks like it makes so much more sense...
ps, your pictures reminded me I had not posted final pictures of our install. (at least on that thread, I may have done it on another talking about installing the floor) So I went back and added them if you want to see how ours ended up.... Hope that GFCI works for you! Naturally, they are not the cheapest breaker on the shelf.

Thanks for the suggestion on the place to call. I'll do that.

Regarding the hummm in our 2007, it's different than the converter fan coming on. The fan noise we can live with. What bugs us is a hum/buzz (sometimes quite loud) that we get with different electrical loads. Certain combinations of lights being used will cause a very annoying buzz. We can affect the buzz by simply changing the lighting combination, but it's quite annoying to not be able to light the trailer the way we want. Something as simple as turning on the bathroom light or the bedroom light can really affect the electrical noise.

I'm going to get the trailer this weekend and start working on the system. I'll report back what I find, and I'm always looking for advise on how to make the trailer better!

We also have a very bad buzz in our factory installed sound system, but we get the converter hum/buzz even with the sound system turned off completely. The hum/buzz that I think is from the converter does not emanate from the speakers.
