There has been alot of talk of late about the virtues of backing up your workstation with a UPS. Being green on this subject, I was looking for some recommendation. Something with a small footprint to fit in with my newly acquired workstation would be a bonus. What say you all?

As per Alan's link the Trust 1000VA is the one I use

They weigh a bit but are worth their weight in gold. Not just for power out situations but they clean up the power supply nicely too.

I bought the above after working in a park for 5 weeks in temperatures of -5 C and the park staff kept plugging a heater in which took out the mains supply regularly. As we were in the middle of a field you would on occasions see the lights dim so the supply was pretty poor anyhow. Once the UPS was fitted I had no further problems with lock ups and when the main supply was tripped I was able to shut down without data loss.

Every event system should have one :D

Ensure they will work with a generator - some don't.

I found out the hard way many years ago.... :-(

It's all to do with the UPS not seeing the input power as clean or stable enough and not changing back to incoming power, it's not an issue with mains power in the office but maybe out in the field (so to speak)

Usually an on-line ups will work fine (they are dearer)

Thanks boys for your comments.....

How BIG (and heavy) are these things? They look like the proverbial brick to me and quite frankly I can do without the weight. Stu's point about a UPS being able to work with a generator is a valid one. It's the one great thing about working with laptops. Their UPS is built in.....

:pce: :puter:

Hi John

the one I put the link to is not very big - two house bricks one on top of the other and a bit longer or 13L x 4W x 6H (inches). Weight wise about 5Kg.

Bear in mind this linked UPS is specified as modified sine wave( that really means stepped square wave) and may not be suitable for all equipment - ideally output should be pure sine wave.
