Airstream Univolt

Airstream has used many different power converters and distribution panels over the years and the name "Univolt" has been commonly termed for all of them.  Some of the original units were actually labeled "Univolt"  Today's technology is far advanced from the old Univolts and a modern switch mode converter will undoubtedly increase the performance of your DC system and battery charging capability.
Many older "Univolts" also housed the DC distribution fuses as well.  Since these are no longer produced, a separate fuse panel must be installed.  This is not a difficult job.  Here is a typical wiring diagram (Look at the second page) to illustrate installing a modern deck mount converter with a separate fuse panel. 
If your unit has a separate DC distribution panel located on a wall for instance, you do not need a new fuse panel unless you want to replace glass fuses with modern automotive blade style fuses common in new RVs. 
When installing a modern converter, you will not have use of the AC power-on light found in most Airstream control panels.  Here is the Bill Worden method to make the power-on light work when connected to AC shore power. 
Most any deck mount converter can be used to replace the older Univolt however we recommend the Powermax Boondocker.  They are very reliable, efficient, have a great 4 stage charge profile and the best warranty (3 years)

Newer Airstreams use the Parallax 7355 power center with a single stage converter/charger section.  If you wish to upgrade to a 3-stage charger, we have the upgrade kits.
