Uninterrupted Power Supply - Question

02/28/2006 11:16:30 AM · #1

I am looking for a battery back-up for 2 telephone answering machines at work (where customers leave orders overnight). The only ones that I have found only last for 15 minutes to 2 hours; I am looking for a longer period of protection. Am I looking at the wrong items or am I misinterpreting the descriptions.

Ideally, I am looking for protection from power outages for two answering machines so we do not miss any orders. Any input?

Those times are for the unit under full load. Answering machines would not consume near as much power. I have two 650S units. One has the computer and monitors and the other has the modem, router, printers. When the power goes out, the one with the modem and stuff will stay powered up for hours as the draw is not that much.

I have used the modem on battery with my laptop and the battery on the laptop ran down before the modem lost power.

The time they stay powered up is governed by the load on the battery.

Thanks for the reply--
Any specifications that I should be looking for? Or Models/manufactureres that you would recommend?

Sorry just re-read your response- What make is 650s and do you think that that would be a good choice for me?

Here is a good link explaining exactly how to determine the size of the UPS you will need.

I have only ever owned APC UPS' both at work and at home. I have never had a problem and replacement batteries if needed always arrived quickly (once each in my older units - 10 years old and still working, both had the batteries replaced in the 7th year of use).

Try this for size. Now this is a UPS.

I believe Alienyst was suffering from Fat-Finger Syndrome and meant to type 650W or 650 watts, which would make sense as a power rating for a UPS. The S is just below the W afterall...

I have a Belkin that has saved my skin as often as not. You'd think in a 'big' city that blackouts would be short and rare, but my neighborhood has several a year that go for up to 4-8 hours which the UPS can't help with.

No Alienyst did not suffer from Fat Finger syndrome. 650s is the model number of the units I have. This particular model is not made anymore. The model now is called Back-Ups Pro and is slightly different. The s on my model number indicated the type of communication to the PC it uses - serial. It is 650 va though.
