Sustain critical workloads through outages, brownouts, and unstable utility power with APC Smart-UPS On-Line protection sized for demanding IT environments. The SRT10KXLT delivers 10,000 VA / 10,000 W of double-conversion power conditioning at 208 V, producing pure sine wave output for servers, storage, network gear, and converged infrastructure that cannot tolerate transfer gaps or waveform distortion. Built for rack deployment, this model fits environments where uptime, power quality, and serviceability matter more than lowest upfront cost. The hard-wire 3-wire input and multiple NEMA L6 outputs support structured power distribution in data closets, edge rooms, and small server suites. Extended runtime capability gives teams room to ride through short outages cleanly and shut down gracefully during longer events. APC’s Smart-UPS platform adds the operational visibility and integration points infrastructure teams expect, including USB, serial, contact closure, RJ-45 10/100 Base-T, and Smart-Slot support. That makes it easier to align the UPS with monitoring and management workflows already in place. With a 3-year limited warranty and battery coverage separate from the chassis, this unit is positioned for organizations that need a serious power layer, not a commodity backup box.
