APC SRT2200XLA – 2200VA 120V Online Tower UPS

Overview :

The APC SRT2200XLA is a double-conversion online uninterruptible power supply designed to provide continuous conditioned power for critical IT infrastructure operating within a 120V electrical ecosystem. It is deployed by network engineers, system administrators, and facilities teams responsible for maintaining uptime for servers, network switches, storage appliances, and laboratory equipment. The UPS isolates connected equipment from voltage fluctuations, harmonic distortion, and utility outages while supplying battery-backed power during electrical interruptions.

The system delivers 2200VA / 1800W output capacity through a double-conversion architecture that continuously converts incoming AC power to DC and back to AC. This topology eliminates transfer delays during power failures and produces a stable sine-wave output with less than 2% voltage distortion. Input power is provided through a NEMA 5-20P plug, and the UPS distributes protected output through six NEMA 5-20R outlets and one NEMA L5-20R outlet, supporting mixed rack or tower IT loads from a single UPS source.

Within infrastructure deployments, the unit is typically installed in branch server rooms, network closets, and edge infrastructure locations where 120V rack power is standard. The tower chassis can operate beside rack cabinets or be installed in rack environments using compatible rack-mount rail kits, occupying 2U rack height when mounted horizontally. This allows deployment within standard 19-inch server racks used in IDF, MDF, and small data center cabinets.

Operational management includes USB, RJ-45 serial, and SmartSlot expansion interfaces for integration with infrastructure monitoring systems and automated shutdown platforms. The SmartSlot enables installation of network management cards for remote monitoring, alerting, and centralized power management across distributed sites. An integrated LCD interface provides local diagnostics and status monitoring for operations teams performing on-site maintenance.

A typical deployment example is a small virtualization host cluster or network aggregation cabinet where stable 120V power is required for switches, firewall appliances, and storage nodes. The UPS conditions incoming power and provides several minutes of battery runtime, allowing systems to perform controlled shutdown or maintain operation during generator startup.

This UPS should not be deployed in environments requiring 208V or 240V rack power distribution, or installations using high-density rack PDUs with L6-series connectors. Facilities operating exclusively on higher-voltage infrastructure require UPS models designed for those voltage ecosystems.
