Interesting. I have a PD9145 in my camper that I installed to replace an old ferroresonant converter. I have had no problem with the 9145 operating from shore power or generator.

I'm strongly suspecting that the PD9160 is not simply a beefier version of the 9145 for 2 reasons: (1) They run at a different switching frequency (I don't remember how I found that out), and (2) Their physical design is so much different (as opposed to the 9180 looking obviously like a bigger version of the 9160). So possibly the 9145 is more tolerant of the input power quality than the 9160, or another possible problem is the 9160's large amount of 50 kHz. trash placed on the incoming power line could be affecting the generator's voltage regulator. I've read that some switching power supplies can severely affect emergency backup generators.

All of the current numbers I listed previously were made while driving a fixed resistive load. When my own PD9160a was pushing 60+ amps its output voltage was pulled down to 13.4 . I don't have the voltage numbers from the person who took the other current measurements.

(I hope that nobody gets annoyed that there are several different discussions going on this one thread).

When a see Wayne's name on a post I always read with eyes wide open. I'm not willing for my questions about this AVR thing to go off into never never land. My person problem with a MAJOR OEM genset AVR and the est. cost of repair added into vary LARGE big bucks. Now the switching power supplies are added to list of possible reason for adverse effect on the little genneys. The recent failure of a C46540 related to the switching power supply, the best I remember. Don't know the final out come of the investagation into the cause of burned equipment and did Champion pay the bill?
