APC Smart-UPS On-Line, 6kVA/6kW, Rack/Tower, 208V, 2x L6-20R+3x L6-30R NEMA outlets, Network Card+SmartSlot, Extended runtime, W/O rail kit, TAA

The APC SRT6KXLTUS is a Smart-UPS On-Line unit that keeps mission-critical hardware running when the utility power is unstable or unavailable. Delivering 6 kVA or 6 kW of pure sine wave output, it protects servers, storage arrays, network switches, and industrial controllers from surges, brownouts, and outages.

This model accepts a 208 V input and provides five NEMA outlets, with two L6-20R receptacles and three L6-30R receptacles ready for high-draw equipment. It can slide into a standard IT rack or stand upright on the floor as a tower, giving you flexibility in data centers, edge closets, laboratory benches, or production lines. Because the rail kit is not included, you can pair the UPS with mounting hardware that matches your existing rack setup.

An embedded Network Management Card lets you check load levels, battery status, and event logs from a web browser or through SNMP, while the built-in SmartSlot accepts optional accessory cards for additional monitoring or control. During an extended outage, bundled PowerChute software performs an orderly shutdown of physical servers and virtual machines to prevent data loss.

The unit supports extended runtime options, and its lead-acid batteries recharge in about 1.5 hours once power is restored. TAA compliance makes it suitable for federal agencies, defense contractors, and other organizations that follow strict procurement guidelines. Standing roughly 17 inches high and weighing about 135 pounds, it fits environments where space is at a premium but uptime is essential.
