"Overview\nTripp Lite's HT850UPS line-interactive UPS offers complete protection for PCs, workstations and other sensitive electronics in an ultra-compact, mountable housing. Internal UPS circuits support individual VCR\/DVR components as long as 3 hours during power failures. Prevents data loss and system downtime by providing battery-supported AC output during blackouts and automatic voltage regulation (AVR) during brownouts and overvoltages. Includes 12 output receptacles, 4 of which are widely spaced to accommodate large transformer blocks without obscuring adjacent outlets. 6 outlets offer full battery support and surge suppression, protecting computers, monitors and other vital system components from power loss. 6 additional outlets with surge suppression only are ideal for printers and other peripherals not requiring battery support. Single-line telephone suppression jacks protect modems, fax machines, cordless phones or other equipment with a DSL or standard dialup RJ-11 phone line connection. Set of gold coaxial line surge suppression jacks protect CATV, satellite or broadcast antenna connections. USB communications interface with PowerAlert monitoring software (free via web download) and cabling enables a safe, unattended system shutdown.
