MGE EPS 2000 UPS available

Ok, it's not a computer, but it's certainly computer related... i have an MGE systems 50KVA UPS available that we just removed from service yesterday. Unit has been running for 10 years ( we moved up to a newer unit ) under maintenance from MGE. This is a 480VAC 3phase input, charging a string of 40 batteries at about 512 volts, and providing an output of 220 3phase through a step down transformer. It's a big heavy thing, approx 1700 lbs for the UPS and same for the battery box, in a stage of partial disassembly now ( to get it out of the room it was in ). Best part is it's free... just come by and pick up ( liftgate truck is required... its heavy and we don't have a loading dock ) We're located in Tucson AZ. It should be a matter of nuts and bolts and having a good electrician to reassemble this fellow if you wanted to bring the whole thing up or.. if you have one of these, it's a great source of spare parts ( since they aren't made any longer ) Mike
