Used in excellent condition. When I say fully tested, I don’t mean that it was powered on and off and started the pump motor. It was used to ramp RPM up and down through all speeds and checked for no “over current fault” codes which are a common problem with working but used drives, as the electrolytes in the capacitors age. This one is trouble free. My testing routine requires that this drive run 4 hours at 2,250 RPM, then 4 hours at 3,000 RPM and an entire hour at maximum RPM in quick clean mode on my own home pool. It’s just a ton of trouble, inconvenience and expense that I never want to go through again so I put anything I sell through rigorous, video documented testing to protect us both.
