Maintain uptime for switches, routers, servers, POS terminals, and network hubs with a rack-mount UPS built for dense IT environments. The APC Smart-UPS Li-Ion SMTL1000RM2UC combines 1,000 VA / 800 W capacity with lithium-ion battery technology to support critical loads in a compact 2U footprint. Designed for 120 V environments, it accepts a wide 82 V AC to 144 V AC input range and delivers 120 V output to help stabilize connected equipment during brownouts and short interruptions. Six NEMA 5-15R outlets provide direct connection for essential devices, while the rack-mountable chassis fits cleanly into standard infrastructure layouts. Lithium-ion chemistry is a practical advantage where service access is limited and uptime matters. Compared with conventional battery systems, it supports a 3-hour recharge profile and reduces the maintenance burden associated with frequent battery replacement. The 5-year repair-or-replace warranty adds further confidence for teams standardizing on long-life power protection. For edge closets, branch offices, and distributed network rooms, this model delivers the right balance of runtime support, rack efficiency, and battery longevity without overcommitting space or service time.
