Help choosing a UPS

Last response: in Components
Share

I need to find a UPS that will provide me with at least 10 minutes of running time for all the listed equipment below

-(2) 32" LCD Vizio televisions
-(1) 25" LCD HP monitor
-(1) Sprint AirRave Wireless Access Point
-(1) Plantronics headset with AC adapter
-(1) two line IP phone
-(1) Belkin wireless router

The computer on the above system is an HP Laptop so it will default to battery in case of power loss.

-(1) 20" LCD monitor
-(1) Tower PC with a 500w p/s
-(1) HP All in one Inkjet scanner/fax/printer

Both machines are mission critical to my business. I live in an area with a decent power grid but these machines must be up 24/7/365 so I need at least 10 minutes to spare in the event of an outage so I can activate my offsite.

I am sorry that I don't have specific power consumption rates for my equipment. I hope you guys with your infinite experience will be able to 'ballpark' some thing for me. Overkill is ok. A nuke from orbit when a firecracker will work is not. =D

Thanks for any and all replies.

Tower PC with a 500w p/s

Is the 500 Watt power supply in that PC able to run on a UPS that outputs a simulated sinewave while operating on battery backup power or is a pure sinewave UPS a necessity? Guessing will just lead to recommending a UPS that may not even work properly with your equipment (i.e. the UPS will fail to switch over to battery power or the UPS will detect an overload condition and shut itself down).

Please provide the brand and model number of the PC if it's a consumer desktop system from a brand like Acer, Compaq, Dell, Gateway, HP, ..., etc.

Is there any way that you can provide model numbers for each device?

There may be several different models for each device, with each model having vastly different power consumption values in some cases, making it very difficult to even arrive at an adequate UPS solution.

Here's an example of what is encountered for an HP 25" LCD monitor:

HP w2558hc: 130 Watts maximum

HP 2510i: 60 Watts maximum

HP 2511x: 40 Watts maximum

The All-In-One printer is an HP Officejet J4680
Monitor on Tower is an Acer AL1914
Tower is an HP 6313w
Monitor 1 on Laptop side is an HP 2159m
Monitor 2 on Laptop side is a Vizio E320VA
Monitor 3 on Laptop side is a Vizio E321VL
Laptop is an HP Elitebook 8460p with a docking station (necessary to power dock to feed signal to multiple monitors.)

I do not have model information on the headset, phone, or Wireless Router.

I hope this is enough and thank you for being patient with me. I'm new to all this and am learning as I go.

Using a conservative load estimate of 650 Watts and a desired runtime of at least 10 minutes:

APC Smart-UPS 1500VA LCD 120V
Model: SMT1500
Output Power Capacity: 1000 Watts / 1500 VA
Estimated Runtime: 14 minutes @ 650 Watt load

APC Smart-UPS 2200VA LCD 120V
Model: SMT2200
Output Power Capacity: 1980 Watts / 2200 VA
Estimated Runtime: 37 minutes @ 650 Watt load
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

You can look for other brands, models and price levels if you desire to. Just make sure that the UPS model is actually rated to handle a load of 1000 Watts or more so that you will be able to get the runtime you need or longer.
