Tripp Lite's SMART1200XLHGL medical-grade UPS system provides dependable lithium iron phosphate (LiFePhos) battery backup, so you can work through short power failures and perform an orderly system shutdown in a prolonged blackout. It's fully compliant with UL 60601-1 regulations when plugged into a hospital-grade outlet, making it ideal for use in patient-care vicinities. The 1kVA/750W capacity provides up to 28 minutes of runtime for a half load and 10 minutes for a full load. Built-in line-interactive voltage regulation corrects brownouts as low as 81V and overvoltages as high as 143V to normal 120V nominal output, without drawing battery power. A built-in isolation transformer with Faraday shield offers full isolation and removes common mode noise while maintaining full AC surge suppression in all modes. It also reduces the cumulative leakage current of connected equipment to less than 100 ?A. Floating AC output prevents noise coupling from noisy hospital ground systems. This UPS system features four NEMA 5-15R-HG hospital-grade outlets and has a hospital-grade NEMA 5-15P-HG plug with a six-foot cord for flexibility in placement. All four outlets provide both backup protection and 940 joules of surge protection. The SMART1200XLHGL also features diagnostic LEDs, as well as a USB port and a DB9 serial port that work with Tripp Lite's free downloadable PowerAlert® software for safe, unattended system shutdown and file saves in the event of a prolonged power failure.
