Eaton 9SX1500I 1500 VA 1350 W Tower UPS

PRODUCT OVERVIEW

The Eaton 9SX1500I is a 1500 VA / 1350 W online double‑conversion uninterruptible power supply (UPS) engineered for critical IT loads and professional environments where power quality, availability, and continuity are essential. Built in a robust tower form factor, this UPS continuously conditions power, isolating connected equipment from mains disturbances such as surges, sags, frequency anomalies, and electrical noise.

True Online Double‑Conversion Technology

Employing online/double‑conversion topology, the 9SX1500I regenerates AC output regardless of incoming mains quality, delivering a pure sine‑wave output with a 0.9 output power factor. This means the UPS can support 1 350 W of real usable power from its 1 500 VA rating, making it suitable for servers, storage systems, networking equipment, and edge computing infrastructure with modern active‑PFC power supplies.

The unit features six IEC C13 outlets for flexible load connection and supports a wide input voltage range (190–276 V without derating, extendable to 120–276 V with derating) and frequency tolerance (40–70 Hz), enhancing robustness in regions with unstable utility power.

Battery Backup & Expandability

Internally, the UPS uses four sealed lead‑acid batteries (12 V/9 Ah) managed with Eaton’s Advanced Battery Management (ABM) and temperature‑compensated charging to enhance battery life and reliability. Batteries are hot‑swappable, allowing replacement without powering down connected equipment, and the system automatically recognises external battery modules (EBMs) for extended runtime when longer autonomy is required.

Typical backup durations include around 16 minutes at half load and ~5.5 minutes at full load, offering sufficient time for orderly shutdowns or transition to alternate power sources during interruptions.

Connectivity, Management & Indicators

For intelligent monitoring and control, the 9SX1500I includes:

• USB (HID‑compliant) and RS‑232 serial ports for direct communications

• Dry contacts and mini terminal blocks for remote power off and signalling

• One expansion slot for optional communication cards (e.g., SNMP/Web)

• A multilingual graphical LCD display showing real‑time operational data (load, battery, input/output metrics)

The UPS integrates with Eaton software such as Intelligent Power Manager and Intelligent Power Protector for automated shutdowns, event logging, and management within virtualised and multi‑platform deployments.

Design, Compliance & Operational Attributes

The Eaton 9SX1500I operates quietly (< 43 dB at 1 m) and supports standard IT ambient conditions (0 °C–40 °C; 0–96 % non‑condensing humidity). It carries multiple international safety and performance certifications including IEC/EN 62040‑1, IEC/EN 62040‑2, UL 1778, CE, cULus, and EAC — reflecting broad global compliance.

Built for network infrastructure, server closets, and critical workstations, the 9SX1500I balances continuous clean power delivery, expandable runtime, and intelligent management, making it a strong choice for applications where data integrity and uptime are vital.
