As the name suggest, this UPS is suppose to be compliment to the AST Manhattan servers. But my guess is that the sale hasn't gone all that well. Anyway, for 1000VA UPS, it's selling for under $200 -- and it has utilities for several OS (BSD, OS/2, Netware, etc.) for interfacing with it. Of course, it's the price that's attractive. I'm thinking of buying several. One of the personal replies I got said the unit is indeed good, but he's not too well conversed in UPS to know what kind sine wave it produces -- he just quoted me the items in manual. I have looked for UPS from both APC and Tripp Lite, but couldn't recall about sine distortion in "%". I was hoping that either someone has these AST UPS to know what makes it tick, or someone who knows something general/technical about UPS to point me out if this "3% distortion on sine wave output" is indeed a good figure to use. ------------- clip here with virtual scissors -------------- ******************************************************************* Send any interesting roadkills to honge@creighton.edu!
