I bought one, it's a relabeled Indstrial Drives/Kollmorgen BDS4
series. It's for a brushless motor with resolver; the J763101
indicates it is pre-tuned for a specific motor winding. If I read the
internal P/N labels correctly, these units will do a max of 230V, 3A
per phase output - DEFINITELY no more than 6A (wrong unit dimensions).
It takes differential +/- 10V analog input. The IGBT in it is rated
15A, 600V if you are curious.

(I think there are 1 or 2 left on eBay yet...)
