I have no power engineering background. Could someone please explain to me why an uninterruptible power supply necessarily is so expensive? I've been targeting UPS's with fast switching time, or else one which is on-line continuously. I'd like one which can power my Compupro, which s fairly loaded with 12 boards, and my Quantum 40 MB disk, minimum. I can live without my printers or terminals , though 1 terminal is a necessity. Among the names I've looked at are: Clary, Sorensen, Computer Power, Power General, Best Energy, Frontier Technologies, LorTec, Isoreg, Electro Vector, Triad-Utrad, Elgar, Topaz, and Jefferson Electric... Thank you. -- sam hahn [software weenie]
