Re: Line interactive versus on-line UPS

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

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.
