[AusNOG] Who makes good UPS gear besides APC?

[Mark Foster]

I don't know much about Fuel Cells except that I perceived them as the 
'battery' not the 'UPS'.  You still need the tech to run your gear and 
switch you between primary and backup power supplies, don't you?

Another vote for Emerson, by the way.  Had nothing but good service out 
of both their equipment and themselves, supporting their kit.
I use Emerson for my 'enterprise' UPS suite and APC gear for smaller, 
self-contained rack mountable stuff.

I had some Eaton PDU's once, they really weren't that great at all, I 
hope their UPS's don't fall into the same category...

Mark.

A couple of rectifiers and some deep cycle batteries would be overkill for most small requirements. I think the open compute project is trying to go down that road.
