This VFD was hooked to 3-phase 400V instead of its intended 230V and blew some stuff
Now, I am quite aware it may have blown more then just the visible damage, and that it is likely never going to live again.
But I am intrigued by the fact these obvious electrolytic buffer capacitors have no proper markings on them.
No voltage, not capacity, no temperature.
They show as Rubicons, and the brand and quality and source of the VFD is such that I have no reason to doubt it.
Searching the net only shows Rubicons with normal specs.
Is this sort of labelling by Rubicon normal?
Does it mean these are build to spec for this VFD maker specifically?
So the numbers are CB1286 H01 and D29344 and 151882 (the latter is probably some production run or datestamp)
See images
Also, while I am posting: This obvious inrush limiting NTC is labeled TH3.
Anyone has any idea on those specs?
Thanks
