APC SRT5KRMXLTUS Smart-UPS On-Line 5kVA, Rackmount 3U

APC SRT5KRMXLTUS 5000VA Online Rack/Tower UPS

Overview

The APC SRT5KRMXLTUS is a high‑capacity double‑conversion online uninterruptible power supply intended for mission‑critical IT infrastructure where continuous conditioned power is required. Infrastructure engineers deploy this UPS to protect servers, storage arrays, network switches, and virtualization clusters from utility outages, voltage fluctuations, frequency instability, and electrical noise. The online topology ensures that connected equipment receives power from the inverter at all times, eliminating transfer delays and isolating loads from upstream anomalies.

This model delivers 5000VA / 4500W output capacity with pure sine wave output suitable for enterprise‑class power supplies using active power factor correction. The unit operates with 208V nominal input and output voltage and typically integrates with building power distribution systems feeding rack cabinets or edge data center equipment. Power connections include a hardwired input or configurable plug option and multiple L6‑series receptacles for downstream distribution to protected devices.

The chassis supports both rack and tower orientations, enabling flexible deployment in standard 19‑inch cabinets or equipment rooms where floor space is available. In rack installations the unit occupies 5U of rack height, and it can also function as a standalone tower where rack mounting is impractical or space is constrained. Optional external battery modules can be added to extend runtime for longer supported outages.

Management and monitoring of this UPS are provided through integrated network management capabilities with Ethernet connectivity, SmartSlot expansion for interface cards, and USB/serial communication. Administrators can monitor load levels, battery status, and event logs through infrastructure management systems, enabling coordinated shutdowns during extended outages and integration with broader monitoring frameworks.

A typical deployment includes a rack supporting virtualization hosts, aggregated networking equipment, and storage arrays. In this environment the UPS maintains conditioned power while providing sufficient runtime to allow virtual machine migration, controlled shutdown, or high‑availability failover procedures.

This UPS is not intended for small branch racks or low‑power edge closets. Environments requiring moderate capacity power protection typically deploy lower‑capacity UPS systems with lower VA ratings.
