But are the semiconductors and capacitors of high quality?
Ease of use is important but not as important as blown parts. I don't want shady transistors, bad thermal design, etc.
ABB is good on these? Guess I am mainly worried about the electrolytic capacitors and the main drive power transistors. I am thinking about it like another bit of test gear to put on a bench then application specific, if that helps model/manufacturer choice any
