Replacement Converter PD9270v

For easy direct board replacement consider the WFCO-Powermax Main Board Replacement.

I recommend the 35 or 45 amp for 1 or 2 batteries and the 55/75 amp for 3+ batteries.

Its a good unit. I would also consider the Powermax Boondocker 75. Similar money and a better warranty. The Iota is nice too but more money. Check out bestconverter.com Reasonable and great folks.

The PD units are IMHO a definite improvement over the WFCO units. WFCO are not known for going into bulk mode charging for most users.

If you dry camp and use a 2000W or smaller generator, I'd recomend the PD60A unit over a bigger one. The reason is that the 60A is already near the max continous rated VA for many 2000W generators. The actual current draw is near 1500VA (much higher than the watts, related to the poor power factor) when charging well discharged batteries. The 70A unit may push you over the edge with a 2000W generator, especially at higher temps and high altitude.

If your not "generator" limited, go for whatever will fit.

I have a PD9260 leave it plugged in all the time at home, maintains the battery fine (two 6V GC are now 6 years old with no apparent loss of capacity). We dry camp often, and the unit has great output when recharging from gen.

The 9260 replaced the original 45 Amp single voltage converter installed in the power center(actually left original in place as an emergency backup). Required installing unit in a different location. I moved it from the original power center where it was too big to mount to a compartment next to the batteries. Used battery cables from a local automotive store to wire the system from the converter to the batteries to essentially eliminate any voltage drop between the converter and batteries. Extremely happy with the results.

I have the PD9270 in my 2003 Pace Arrow. It is great leave it plugged in all winter with no problems.
