Eaton SMX3000XLRT2UA – 3000 VA Line‑Interactive UPS 208 V

Overview

The Eaton SMX3000XLRT2UA is a line‑interactive uninterruptible power supply (UPS) designed to protect critical IT equipment in rack and tower environments where power continuity and conditioned output are required. It is typically deployed by IT engineers, network architects, and facilities teams in branch offices, wiring closets, and light‑to‑medium data halls to shield servers, storage, network switches, and telecommunications gear from brownouts, surges, and complete utility failures. The line‑interactive topology with automatic voltage regulation (AVR) corrects undervoltage and overvoltage conditions without immediately switching to battery, preserving battery life while maintaining usable output voltage.

Rated at 3000 VA / 3000 W with unity (1.0) power factor and pure sine‑wave output, the unit supports rack‑mount infrastructure loads that demand stable power and high usable capacity. Output voltage can be set across multiple nominal values (200/208/220/230/240 V), supporting regional distribution standards. The UPS uses internal Valve Regulated Lead Acid (VRLA) batteries that are hot‑swappable for field service and supports optional external battery packs (BP72VRM2U) to extend runtime during prolonged outages.

Deployment is typically in 2U rack space using the supplied rail kit, but the unit can also be used in tower orientation with included support stands. The front LCD display provides real‑time status on input/output conditions, battery charge, load, and operating mode, enabling local diagnostics without auxiliary tools. Integrated USB and DB9 serial connections support local monitoring and controlled shutdown scripting via Eaton’s PowerAlert software; a slot for optional network management cards (e.g., WEBCARDLXE) enables 24/7 remote access and alerts (network card sold separately).

A practical deployment example is backing up and stabilizing power for a core consolidation rack with virtualization hosts, SAN storage, and uplink switches. The unit’s AVR improves tolerance to brownouts on poorly conditioned feeds while the battery bridge allows orderly shutdown or handoff to standby generation. Runtime scaling with external battery modules enables extended outage coverage based on site requirements.

This UPS is not suited for environments requiring full online (double‑conversion) isolation or where continuous generator operation coordination is needed; in such cases, true online double‑conversion UPS families should be selected. Additionally, it does not provide outlet‑level switching or advanced network management out‑of‑the‑box without optional accessories.
