We had a PDP with one non-functional output. Replaced it and continued with the season, saving the bad unit to inspect later. The damage to ours appears to be similar to the one discussed in an earlier thread.
I don’t recall what kind of load was on the output that went bad. This PDP was used in several tests of candidate mechanisms, so it seems likely that we stalled a motor on it at some point.
So noble of the $200 PDPs to sacrifice themselves to keep a couple of $7 breakers from tripping!
Seriously, we smoked a CIM this year by stalling it against a hard stop (programming error, and no one who heard the clicking of the breaker said anything). We plugged a new Talon SR (just in case, because the color was funny) and CIM into the same port on the PDP, no issues. [Speculation] This makes me think that there was a dead short on the line resulting in the trace being a lighter fuse than the slow-blow breaker, or some pre-existing flaw with the trace.
