The APC Smart-UPS RT 15kVA, 208V is a purpose-built online uninterruptible power supply engineered to protect critical IT infrastructure in data centers, server rooms, and network closets. This rack-mountable unit combines the robustness of online, double-conversion power with a compact 12U form factor, making it a reliable heart for multi-server environments, virtualization hosts, storage arrays, and essential networking gear. With an intuitive LCD interface, a diverse outlet configuration, and a lead-acid battery included, the Smart-UPS RT delivers clean, precise power to your equipment while minimizing downtime and ensuring graceful shutdowns in the event of outages. In environments where every watt matters, this 15kVA, 208V UPS provides the performance you need and the reliability IT professionals demand.

• Online, double-conversion protection for sensitive equipment

  The Smart-UPS RT operates with true online power conversion, continuously filtering and regenerating energy to deliver a clean, stable 208V output. This topology isolates voltage sags, transients, and harmonic distortion from your critical devices, helping prevent data corruption, unscheduled reboots, and hardware wear. The result is proactive protection for servers, virtualization hosts, storage systems, and networking gear—even during severe power events or irregular utility power quality.

• High-capacity power with reliable runtime for critical workloads

  With a 15kVA rating and 12kW of usable output, the APC Smart-UPS RT provides ample headroom for dense rack installations. It supports multiple servers, switches, and storage nodes within a single enclosure, enabling consolidation and simplified power management. The design prioritizes uptime, giving IT teams the time needed to initiate graceful shutdowns, perform maintenance, or switch to alternate power sources without risking data loss or service interruption.

• Flexible outlet configuration to support diverse devices

  Four NEMA L6-20R outlets and two NEMA L6-30R outlets give you a versatile mix of protected receptacles to accommodate a range of devices in a single rack. This configuration simplifies cabling, reduces the need for additional power strips, and ensures critical components—such as servers, PDUs, network switches, and storage controllers—remain on protected circuits during both normal operation and outages. The layout supports organized power distribution and efficient load balancing across the rack.

• Rack-mountable design with an integrated LCD interface

  The 12U rack-mountable form factor fits standard 19-inch racks, preserving valuable floor space in data centers and IT closets. An integrated LCD panel provides at-a-glance visibility into real-time status, input/output voltage, load level, battery capacity, and event history. With clear navigation and status indicators, administrators can perform quick checks, monitor performance, and troubleshoot without external tools, reducing downtime and accelerating response times during incidents.

• Reliable lead-acid battery system designed for dependable uptime

  Included is a lead-acid battery pack built for predictable runtime and straightforward maintenance. The battery system supports routine health checks, self-tests, and scheduled replacements to preserve uptime in demanding environments. Regular monitoring of battery health helps prevent unexpected outages and ensures the UPS remains ready to protect critical workloads when utility power is interrupted.
