We have a 5KVA Best Ferrups here that has never worked correctly.... :-) But I've seen my share of toasted APC's, too. Currently we run older APC SmartUPS (pure sine) for the workstation stuff and Symmetras in the Data Centers. Looking to put in a Toshiba or similar 500KVA in the secondary Data Center later in the year. > BTW, another thing the 'good' UPS's do, more important than 'pure > sinusoidal output' for computer purposes*, is buck/boost voltage regulation.

Or old 3Com Corebuilder/CellPlex 7000 gear, which shuts down with anything but pure sinewave..... _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
