Eaton SMART1500RT1U – UPS 1440 VA 1100 W

Overview

The Eaton SMART1500RT1U (marketed under Tripp Lite by Eaton) is a 1440 VA / 1100 W line‑interactive uninterruptible power supply (UPS) designed to maintain conditioned AC power and limited battery backup for rack‑mounted IT gear, network storage, telecom, and critical edge devices. It targets IT engineers and facility operators who require regulated output and short hold‑up time to preserve data integrity and enable orderly shutdowns during power anomalies.

This UPS delivers nominal 120 V AC output with automatic voltage regulation (AVR) to correct undervoltages and overvoltages (bolstering stability down to roughly 90 V) without immediately engaging battery resources. Its topology is line‑interactive, providing fast transfer (≈8 ms) when utility power deviates beyond acceptable thresholds.

A 1U rackmount/tower convertible form factor maximizes use of constrained cabinet space while offering flexible deployment in server rooms, IDF closets, or compact racks. A front panel with LED indicators and an LCD interface reports real‑time line, battery, and status data for on‑site diagnostics.

Connectivity includes a USB HID‑compliant port, RS‑232 (DB9) serial interface, and an EPO (Emergency Power Off) terminal; an optional network management card slot supports remote monitoring and control when equipped. Internal hot‑swappable VRLA batteries allow service without taking equipment offline.

Hold‑up time is limited to a few minutes—typically ~2 min at full load (1100 W) and ~8 min at half load (~550 W)—sufficient only to save work or trigger graceful shutdown procedures. Its capacity and topology make it inappropriate for extended runtime missions or high‑availability core infrastructure.
