Eaton PowerWare 20 kVA UPS teardown
« on: October 16, 2018, 08:19:50 AM »
Here is a little quick, dirty and early morning junk yard teardown of a 20 kVA Eaton PowerWare UPS system.

I have earlier taken some of these systems apart and you can see the differences from there photo galleries:

I've worked on a few Eaton boards (design / modify), though I don't recognize anything in this one, maybe it's older than the designs I've seen.

Nothing really to say, just thought that was interesting, and, I guess, maybe you'll get lucky some day and tear down one that I recognize! ;D

You got quite of lot of re-usable parts out of this one Mads.
Shame about the terminal blocks getting busted up, still could be worse.

Out of interest, do you just give any wiring/cables you don't need to the junkyard, or just toss it back into the cabinet ?

Aha, I recognise a lot of stuff in this video.

A few years back I came across the toss-out pile of a UPS company that was moving premises and scored a bunch of PCBAs that match what Mads has here (along with a lot of other goodies) - nice to know what they were actually out of!

It seems that quite a lot of this model gets thrown out within the last few years, so they have matured for replacement, if you worked on newer stuff, I will see that in some years ;)

Yeah its much more of a shame when its the IGBTs that are cracked. Part of staying good friends with a scrap dealer is that when i take stuff apart, i sort stuff i get loose in iron, cable and copper, thats like free labor to him and i was doing it anyway to get things out. Nothing lost, all to gain :)
