1.5kVA/1.35kW/120V Long-Term Battery Backup for IT Installations and Edge NetworksThis 9PX rack-mount online double-conversion UPS system provides reliable, low-maintenance battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage valuable IT equipment or destroy data. Ideal for locations that are difficult to access or infrequently maintained, the 9PX1500RT-L is an efficient "set it and forget it" solution. It's ideal power management for education, commercial, financial or healthcare networking components, including Cisco switches and servers.Reliable, Expandable Battery Backup Keeps You Operational Through Power OutagesThe hot-swappable maintenance-free lithium-ion battery modules have a service life of 8 to 10 years. They allow you to work through short power failures and give you enough time to safely save files and shut down your system in case of a prolonged blackout. Exclusive ABM technology increases battery life by 50 percent and closely monitors battery health to provide advanced notice when batteries need replacing. These lithium iron phosphate (LFP) batteries provide 80 to 120 percent more runtime at full load than equivalent lead-acid UPS systems while weighing up to 40 percent less, reducing the overall UPS weight.Supports External Batteries for Scalable Extended RuntimeFor mission-critical applications demanding continuous uptime, the UPS supports the connection of up to four expanded battery modules (9PXEBM48RT-L, sold separately) for hours of extended runtime.Optional Gigabit Network Interface Offers 24/7 Remote AccessThe Network-M3 network card (sold separately or as a network card bundle) enables full remote configuration and management, including load shedding, reboots of connected equipment and safe shutdowns. UPS firmware can also be flashed remotely through the Network-M3 without dropping the loa
