Eaton 9PX2000RTN‑L – Online UPS 2000 VA 1800 W 120 V

Overview

The Eaton 9PX2000RTN‑L is a rack/tower online double‑conversion uninterruptible power supply (UPS) designed to deliver conditioned AC power and battery backup for critical 120 V infrastructure loads. It is deployed by data center engineers, network architects, and facilities teams to protect servers, storage appliances, network switches, and virtualization hosts from utility power anomalies such as sags, surges, brownouts, and frequency deviations. The online double‑conversion topology fully regenerates the output waveform, isolating connected loads from mains fluctuations and providing a stable true sine‑wave output.

This UPS provides 2000 VA / 1800 W output with a 0.9 power factor and ±1 % steady‑state voltage regulation, ensuring tight voltage and frequency tolerance for sensitive rack equipment. Output receptacles include (6) NEMA 5‑20R and (1) L5‑30R, supporting mixed rack IT loads without additional distribution. The unit ships with lithium‑ion batteries managed by an integrated battery management system that optimizes battery life and supports runtime scaling via up to four extended battery modules (EBMs).

Deployment is in a 2U rack/tower form factor, including a 4‑post rail kit for standard 19‑inch racks, making it suitable for core racks, consolidation points, and enterprise wiring closets where 120 V AC service is standard. A Gigabit SNMP/Web network card is pre‑installed in the Mini‑Slot expansion port, enabling remote UPS monitoring, event logging, and integration with Eaton’s Intelligent Power Software Suite for controlled shutdown scripting and power event alerts. Local status and configuration are available via a graphical front panel display.

Communications include USB (HID) and RS‑232 serial interfaces, along with remote ON/OFF and relay contacts for integration with infrastructure management systems. The UPS also includes an internal bypass to maintain load continuity during maintenance or service without interrupting protected equipment.

A practical deployment example is protecting a consolidation rack containing essential servers, SAN/NAS storage, and core aggregation switches. During utility power faults or outages, the 9PX2000RTN‑L’s online double‑conversion topology provides uninterrupted, regulated power while optional EBMs extend available runtime to bridge to standby generation or controlled shutdowns.

This model is not suitable for small branch closets or edge wiring rooms where lower‑capacity line‑interactive UPS models suffice. It also lacks modular power stages and internal maintenance bypass cabinets found in larger enterprise UPS products with swappable power modules.
