Intuitive LCD interface High frequency design Auto recognition of external batteries Predictive replace battery date Green mode Energy meter Pure sine wave output on battery Multiple switched outlet groups Intuitive LCD interface Provides clear and accurate information in multiple languages with the ability to configure the UPS locally with easy to use navigation keys. High frequency design Reduces or eliminates bulky transformers resulting in lighter units for ease of handling. Auto recognition of external batteries UPS recognizes when external battery packs are attached and automatically adjusts runtime. Predictive replace battery date Dynamically provides the month and year when battery replacement is recommended to aide in long term maintenance planning. Green mode Patent-pending operating mode that bypasses unused electrical components in good power conditions to achieve very high operating efficiency without sacrificing any protection. Energy meter Provides actual kilowatt hours of usage for energy conscious users. 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. Multiple switched outlet groups Multiple outlet groups that may be controlled separately from the UPS for discrete reboot of hung devices, sequenced on/off and non-critical load shedding.
