Available in 45 or 55 Amp models, Our Ultra III kit is designed to replace Magnetek, B-W Manufacturing, and Parallax 6300 or 7300 Series lower converter-charger sections.  All kits have built-in 3-stage charging and 100% filtered DC output* No cutting or splicing required. For additional photos, check out our converter upgrade link.  

Output voltages are (13.2 VDC Float, 13.6 VDC Normal, and 14.4 VDC Boost) and best of all, the charge technology is already built-in to the converter.  No need for an external charge module.

Kits include the converter/charger, new DC fuse block, two 30 Amp fuses, AC pigtail, 6 AWG DC wires, and all hardware necessary to make the conversion.  Simple to install.  

* If you look at the back of your existing DC fuse block, positions 1-6 are not filtered from the battery because they do not connect to the battery positive lug.  Positions 7-9 are filtered but only if you have a battery installed.  With the new fuse block, all nine branch circuits are filtered with or without a battery, to provide clean DC output to ALL of your DC appliances and accessories.  The two additional 30 Amp fuses are provided for reverse polarity protection.  The new fuse block mounts in the exact same position, using the existing holes and supplied screws.
