APC SRT1500RMXLA 1500VA 120V Rackmount Online UPS

Overview :

The APC SRT1500RMXLA is a rack-mount double-conversion online uninterruptible power supply designed to provide continuous conditioned power to rack-based IT infrastructure operating in a 120V electrical ecosystem. It is typically deployed by infrastructure engineers and network administrators responsible for protecting servers, storage arrays, and network switches in server rooms, network closets, and edge computing environments. The UPS isolates connected equipment from voltage fluctuations, frequency instability, and utility outages while providing battery-backed runtime for controlled shutdown or generator transfer.

The system delivers 1500VA / 1350W output capacity using an online double-conversion topology. Incoming AC power is continuously converted to DC and inverted back to regulated AC output, ensuring zero transfer time during power disturbances and maintaining a stable sine-wave waveform suitable for modern IT power supplies with active PFC. Output power is distributed through six NEMA 5-15R receptacles, while input power is supplied through a NEMA 5-15P plug connected to a 120V branch circuit.

In deployment architecture, the unit occupies 2U of rack space in standard 19-inch server cabinets, allowing direct integration into network and compute racks. The UPS is commonly installed in branch data centers, IDF or MDF network closets, and small enterprise server rooms where rack density and continuous power conditioning are required. The rack-mount design supports installation alongside switches, routers, virtualization hosts, and storage appliances that require stable AC power.

Operational integration includes USB, RJ-45 serial, and SmartSlot communication interfaces, enabling centralized monitoring, remote management, and automated shutdown integration with servers or virtualization platforms. A graphical LCD control panel provides operational status, alarms, and runtime information for on-site technicians performing maintenance or troubleshooting. The UPS also supports Emergency Power Off (EPO) circuits for integration with facility safety systems.

A typical deployment example includes a branch virtualization rack hosting hypervisor nodes and network aggregation switches. The UPS conditions incoming utility power while maintaining battery runtime long enough to allow graceful system shutdown or generator startup.

This UPS should not be deployed in environments requiring 208V or 240V rack power distribution or facilities using L6-series connectors typical in higher-voltage data center power ecosystems.
