Powerware Prestige 3000 UPS repair

MetalHead:
Hi guys!

I have Powerware Prestige 3000P3HV double conversion UPS to repair. Pretty old one..
There is an I*R module (see photo) that I can't identify :(
Does anybody know part number and what is that?[attachimg=1][attachimg=1]

TheMG:
Most likely a custom hybrid module, containing several IGBT and/or MOSFETs.

MetalHead:
Yes, i think so too. Too much legs for diode bridge and while it sits on heat sink it deals with hight currents.. (2000kw inverter or so)
Wondering if I can find a replacement, but as fas as no part number on it chances to find replacement are low

I doubt that. :)

TheMG:
If the module is defective it might be possible with a bit of reverse-engineering to replace it with discrete parts. Might even be able to pop the lid off the hybrid and see the individual dies and internal configuration/wiring.
