@art_of_shred Actual operating load is the most practical.
Is there a simple percentage to use there as a ballpark figure?

How would you measure this in an environment without power monitoring? Or is it basically a guess at that point?
An ammeter works great if you have one and want real numbers.
-
@art_of_shred 70-80% is a safe bet. Sometimes it is lower, but that is typically what I default to when sizing.

Even in the afternoon or do you have to switch to a PMmeter?

Yes! These can be somewhat inexpensive. We usually see IT equipment running at 60% or less of nameplate rating. The challenge we have when sizing a UPS or PDU, and you will have too, is that generic rules always bite you at some point. If you are the exception, you risk taking down everything.
Keep in mind that sizing a UPS or PDU at less than 80% or 100% utilization is a good thing. UPSs and PDUs are like the breakers feeding your Christmas tree lights - Once you add too much, the lights go off!

Once again sporting your prowess in all things electrical. I defer to your expertise...

Couple of ones that might be more home oriented than business:
- Do you have any plans to get into the home battery market, like Tesla? (or are you already) These are the backup batteries that you can charge from solar and then power your home from (or use as a backup for if the power is out).
- What would you recommend in the prosumer market for IT pros or technically minded folks to use at home?

Keep in mind that sizing a circuit at less than 80% or 100% is a good thing. You never want to completely oversize, but UPSs and PDUs are like the breakers feeding your Christmas tree lights - Once you add too much, the lights go off!
Just to clarify, I thought that was worded a little confusingly. You never want your load to equal or surpass your protection. Ideally, your expected amp load should only be about 80% of your protection's full capacity. Otherwise, you can exceed its ability to protect and either diminish its performance or nullify the protection altogether.

That didn't sound good when I read it, so keep your mind out of the gutter.

Too late.
-
Are any of your PDUs capable of being remotely managed? So we can power stuff on / off remotely?
-
Do you offer and trade in discounts for large UPSs to switch to Eaton? We currently have Liebert 3 Phase UPS systems.
-
-
What do you see as the future of battery technology in UPS units? Does lead acid still have a future in these kinds of applications?
-
Looking ahead 10 years what do you see as potentially disruptive technologies that might enter your field?
-
Of your products, is there any one you or the company is particularly proud of? Why?
-
The core of your business is design of power supplies - have you ever considered making consumer/"prosumer" ATX power supplies?

Yes. Here's a closer look at our third generation of rack PDUs: http://powerquality.eaton.com/Products-services/Power-Distribution/ePDU/interact/,

We don't have a formal program--too many variables to factor in for the larger systems. We can certainly connect you with someone local to discuss and/or provide a quote.

@MattSpeller - My take:
Lithium based technologies are great, but who knows how soon they'll come down in price. They're still expensive, many lithium technologies are flammable, and transportation and shipping are becoming more difficult.
There are many 10-year outlooks ahead. The good news is that batteries and energy storage have global research focus from both industry and governments. This should mean the industry will see some major changes in the years to come.
We're really proud of our Intelligent Power Manager (IPM) software. It continues to change the game about how power interacts with IT. We're the first to integrate with virtualization platforms to help manage the virtualization space rather than the physical server alone. We've loved the response from users in the community using these powerful tools and we will continue to provide more benefits in the months to come. Eaton.com/virtualization
The core of our business isn't necessarily power supplies, but power management, a true statement whether it's fuel deliver systems for airplanes, superchargers for top vehicle performance, or UPSs and distribution for datacenters and IT closets. ATX, pro-sumer power supplies are a little out of our focus. We want to position ourselves with products that can improve functionality and interaction for companies that make business happen.

@Nic The home battery market...
-
I think Tesla's play is more on how to re-purpose used automotive batteries, which is still a good thing. The Powerwall is a great step forward for the Grid, but there are a lot barriers to make this an attractive market outside of California and Hawaii.
-
Prosumer market is a tough one. More consumers are shifting to laptops, and far less dependent on peripherals like printers or dedicated monitors these days. That brings to mind the question, why need a battery for basic home use? For people running dedicated servers at home, we certainly have the technology at the right price to keep you up and running. I think the prosumer market has been moving away from battery backup for a while and will continue to do so as technology advances.

@art_of_shred, Well said!

@IRJ Very comparable when it comes to price and functionality. We do offer a 3-year warranty that covers the entire UPS and the battery: http://powerquality.eaton.com/Products-services/Backup-Power-UPS/3S.aspx?cx=3
Typical desktop models:
Eaton 3S: http://powerquality.eaton.com/Products-services/Backup-Power-UPS/3S.aspx?cx=3
Eaton 5S: http://powerquality.eaton.com/Products-services/Backup-Power-UPS/5S.aspx?cx=3The 5S has a nice LCD screen.
We just had a 2.5 hour outage yesterday and I hadn't replaced my desktop UPS yet. I'm ordering this right now (Amazon has it for $200 for the 1500 model.. awesome price!)
