Centurion CS 3000 Replacement
The CS 3000 and 6000 series converters have been discontinued and are no longer available. We recommend the PD 4135 for the CS 3000 series 1200, 2000, 3000. The Boondocker 1245-PC as the replacement for the 4500 (45 amp) and Boondocker 1260-PC for the 6000 (60 Amps) They are multi-stage units, have a much better charging profile and a better warranty. They will fit in the same respective cut outs as the Centurion units.
This could be lurking under your old power center.
