Keep critical systems running through voltage disturbances, transfer events, and extended outages with APC Smart-UPS On-Line protection built for dense rack environments. The SRT8KRMXLT delivers 8,000 VA / 8,000 W at 208 V in a 6U rack-mount form factor, giving infrastructure teams the capacity needed for converged compute, storage, and network gear that cannot tolerate downtime. This model uses online double-conversion topology to continuously condition incoming power and present a clean sine wave to connected equipment. The hard-wire 3-wire input and mixed NEMA output set support higher-load deployments where standard office-grade UPS units fall short. With extended runtime capability and a full-load backup time of 5 minutes, it is designed to bridge short outages cleanly and provide time for controlled shutdown or generator transfer. APC includes the accessories and mounting hardware needed for rack integration, along with management interfaces that fit enterprise monitoring workflows. For teams standardizing on APC Smart-UPS in branch, edge, and core rooms, this unit offers the electrical headroom and build quality expected at this power tier.
