Teardown of a Eaton PowerWare 60kVA UPS system

This is the teardown of a large 2x Eaton PowerWare 60kVA UPS system, first is the teardown video and below are some pictures and a little description of the components. For many more UPS teardown videos, check out the complete list.

Here is a picture of a single Eaton PowerWare 60kVA system installed with battery and inverter cabinets

I am not quite sure if this was really a 60 kVA or a 90 kVA unit, as the cabinet had both stickers on it.

The cabinets were unfortunately badly damaged from crane handling when they were thrown out into the junk yard. I managed to scavenge input rectifier, capacitor bank and 5 inverters from the system. At least the nice big heat sinks and fans were in great shape.

The inverter boards consisted of 10x FS35R12W1T4 IGBT 3-phase full-bridge modules. 6 of them used for the output and 4 of them for the intermediate / battery charge inverters.  For details of the Eaton PowerWare 60kVA boards see the video at the top.

The inverter boards were purely with only IGBT and DC bus capacitors. This makes them suitable for hacking into something else. Maybe it is just the relatively low 70 A peak current handling, that limits its use for other applications.
