APC is fine for DC use where the power is nice and clean in phase. I've seen APC perform pretty poorly though out in the field where the power isn't so clean and VFD's may feed back harmonics in the power circuits.
Whatever you do, consider lifecycle of the device and maybe have a cold spare available ( or change the single PSU device for dual). Nothing is ever foolproof.

Both seem fine to me, we’ve did some pretty solid testing on them when they were installed and setup - only downside to the ION ones is the web management module feels like it’s quite ancient - that being said, I can still get a SNMP trap from them if a transfer occurs which is what I mainly care about on top of the fact that they work On 9 Nov 2017, at 1:08 am, Damien Luke <damien.l...@gmail.com> wrote: We've also had this happen at Global Switch and Metronode over the years, not that unusual but as always it's up to the customer to plan for losing a single feed and cater for single feed devices. I've seen work occur on power circuits at DCs where the operator didn't isolate the feed (aka hot). As much as you plan and ensure your customers are aware of the hazard, all it takes is a sparky to accidentally clip the wrong cable and things go sideways very quickly. The large bang, smoke drifting around the DC and the (junior) sparky falling off of a ladder is a good indicator that hot work is high risk, dangerous and should be avoided as much as possible. I know it sucks that you've got some single in feed gear but gosh I'd rather someone make it home.
