Dell J727N 2700 W UPS teardown
Channel: FFcossag
Date: 2015-11-27

This UPS was scrapped by a local company, for reasons unknown to me. Given that it's a high-voltage battery unit, I'm almost willing to bet that it suffered a battery failure, and the previous owners didn't feel like splurging for a new pack. It's a mid-range, line-interactive job rather than a fully online UPS, so I suppose they might also have wanted to step it up a notch.

I was sad to find out that, even though it has a giant, transformer-looking component inside, it does not offer isolation between the battery and the 230 V output, nor the battery and the mains input.
