Every RV unit has a distribution panel, which is what routes electrical power throughout the unit and includes most of the unit’s circuit breakers and fuses. The RV distribution panel can supply both 120-volt power and 12-volt battery power. Older RV distribution panel models have the distribution center and converter all in one single unit.

When you pull off the top of an older RV distribution panel you will see there is a 120-volt main circuit breaker and each additional breaker for the different appliances inside the RV. You will also see the power cord coming out of the back of the RV distribution panel. The fuses in older models protect 12-volt battery powered systems which power lights, roof vents, water pump and several of the appliance on the LP mode of operation inside the coach of the RV.

The biggest issue with older RV distribution panel models is that the converter is noisier, which can be very distracting when running. The old-style converters also put out of lot of heat, which can create a challenge keeping the coach cool in the heat of the summer. Depending up on the model, it may be possible to upgrade the converter, helping the efficiency of the distribution center.

If you give your RV distribution panel an electrical upgrade you will be able to install a more modern converter that will offer cleaner, quieter power and more efficient battery charging capabilities.

An upgrade is available for just the battery charger portion which can be replaced in the exact spot as the older model. Check availability as some models will need to also upgrade the fuse panel to a newer version.

The newer distribution panels have a separate battery charger that can be installed in an out of the way place, however this type of system is smaller than older models and will require some modifications to the existing cut out placement.

      Thanks for watching the video “Differences Between Old and New RV Distribution Panel Models”. We replaced the original converter only which was a Magnatek model in the ‘92 Suncruiser with a new Parallax Power Supply Series 7300. In the premium version of the replacement we noted that with this new converter an upgraded fuse panel was also required.

      Hope this helps, happy camping!

      Thanks for watching the video “Differences Between Old and New RV Distribution Panel Models” and the opportunity to provide more information on the cost. The model we swapped out was just the converter (battery charger) with a digital version Parallax Series 7300. We got this model from Winnebago’s Customer Service Store and it was $300 suggested retail. I just got off the phone with Parallax and this model has been discontinued and replaced with the model 8300 which can be purchased with just the converter or the entire distribution center in 45, 55, 65, and 75 amp models. I found the 7300 model on the internet in a variety of locations ranging from $100-$800. If you do swap out the old Magnatek with a 7300 model converter, you will need to also change the 12-volt fuse panel. The newer models come with all the components and are more of a multi-stage charge vs the all on like the older system, and have a temperature sensor option. I did a google search on the 8300 and found models from $250 all the way up to $851. As far as a DIY project, it depends on your level of electrical expertise? I would suggest contacting Parallax direct either at http://www.parallaxpower.com or call 800-443-4859 and ask for tech support, they are very helpful!

      Hope this helps!

      Hi Darren. Thank you for visiting the RV Repair Club site and the opportunity to assist with your replacement distribution center. There are a few different upgrades you can do such as the the replacement of the converter only which we did on a ‘92 Suncruiser, or a complete replacement of the distribution center. With that, you can also replace the distribution center with an all-in-one unit that has the converter with the distribution center, or you can get a converter that is separate and installed in a different location. You would need to contact Progressive Dynamics directly to find the correct model for your ‘99 Komfort Travel to verify compatibility as we had to replace the 12-volt fuse panel in our ‘92 swap as well. They can be reached at: http://www.progressivedyn.com/
