APC Smart-UPS SRT 3000VA LCD 120V Rack/Tower Uninterruptible Power Supply

The APC SRT3000XLA is an uninterruptible power supply designed for environments where continuous operation is critical. It delivers 3 kVA and 2700 W of pure sine-wave output, keeping servers, network switches, laboratory instruments, or point-of-sale systems running when utility power falters.

The unit relies on a double-conversion online topology that constantly regenerates incoming electricity and maintains a steady 120 V output. By isolating connected equipment from spikes, sags, and frequency variations, it protects data integrity and hardware longevity.

Eight NEMA 5-20R outlets support standard loads, while one NEMA L5-30R outlet handles higher-draw devices. Hot-swappable battery modules let staff replace batteries without shutting down attached equipment, and additional external battery packs can be added when longer runtime is needed.

An easy-to-read LCD panel shows input voltage, load level, runtime, and alarm notifications. A built-in SmartSlot accepts optional network management cards, enabling remote monitoring through EcoStruxure IT so IT teams can track conditions even when offsite.

Eco mode pushes efficiency up to 97 percent, reducing heat and energy costs in dense rack configurations, branch offices, retail spaces, or medical labs. The UPS installs in either a rack or tower orientation and carries a three-year UPS warranty with a two-year battery warranty.
