The APC SU700X167 is an uninterruptible power supply with auto select input voltage (120V/230V) in and 120V out. Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR). Innovative design allows for fast, easy installation by almost anybody. Automatically starts up the connected equipment upon the return of utility power and prolongs battery life by regulating the charge voltage according to battery temperature. Pure sine wave output on battery simulates utility power to provide the highest degree of compatibility for active PFC (power factor corrected) servers and sensitive electronics.
