Bryan,

In my experience the Line Interactive units don't last as long and certainly don't provide the clean power that a true on-line unit does. This is especially true where the power is poor to start with and the line interactive units have to go in and out whenever the power degrades, flickers, fades, blips or what-have-you. In the old days the on-line units were large, noisy, inefficient, and expensive (like the one in the corner of your computer room!) but today's units are much smaller, quieter and more efficient while doing a better job too. APC makes some nice stuff if you step up to the on-line style, we've installed several of them.

An IBM business partner recommended a 3000VA APC Smart-UPS to replace the
UPS serving our migration tower but when I called a vendor for a quote, the
vendor said he wouldn't recommend a Smart-UPS as they are "line interactive"
units.  Vendor is suggesting an on-line type UPS which costs more but
delivers cleaner power.

Do any of you use line interactive UPS's? Isn't it better to spend a little
more for an on-line unit that delivers cleaner power?
