School me on Power Backup Systems (UPS)

[DAM]

Ok so looking at this UPS from APC it says it has a 5:01 hours:mins run time, yet in the more detailed documentation it says:

Typical backup time
at half load 23.9 minutes (490 Watts)

Typical backup time
at full load 6.7 minutes (980 Watts)

So is the 5:01 hours the run time when nothing is connected to the UPS? I sure hope not, because this is useless stat. Also, by full load they mean all plugs being used?

I am in a bit of a loss here, but I would appreciate some help.


Thanks.

Full load means max wattage. IE If you hook a bunch of monitors up to it, it won't last long. The time it lasts is strictly dependant on how much it has to keep running.

Yeah just figured that out with some cool chart APC has http://apc.com/products/runtime_for_extendedruntime.cfm?upsfamily=165 I am calculating a min of 500VA so I think I will budget for around 700 to be safe, I think I will go with this particular model http://apc.com/resource/include/techspec_index.cfm?base_sku=SUA1500

Thanks.

Just thought I'd add that I own several APC units 350va, and one Cyberpower 1500AVR (I love this one) which weighs a ton but is worth it's weight in gold so don't count out Cyberpower either.

Also consider ebay. I got a Smart-UPS 1400 from APC for $75 from there, shipped!

Does anyone that has one of these encounter the following...

When the power goes out for just a second or so, the ups switches to battery and then back to power.

but

If the power goes out for 5 seconds, then when the power comes back on the ups stays on the battery requiring a shutdown.

Is that normal?

that is not right, you should get that checked because it will eventually lead to the premature death of your batteries.
