Eaton 9PX3000RTN – Online UPS 3000 VA 2700 W 120 V

Overview

The Eaton 9PX3000RTN is a rack‑mountable online double‑conversion uninterruptible power supply (UPS) designed to deliver continuous, 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 core servers, storage arrays, network switches, and virtualization hosts from utility power disturbances. The online double‑conversion topology actively rectifies and regenerates the output waveform, isolating sensitive electronics from mains fluctuations, voltage sags, and frequency anomalies, ensuring clean and stable power.

This UPS provides 3000 VA / 2700 W output with a 0.9 power factor and produces a true sine‑wave output with ±1 % steady‑state voltage regulation for demanding rack loads. Output is delivered through six NEMA 5‑20R outlets and one L5‑30R receptacle, accommodating a mix of server and networking equipment directly without intermediate distribution. The topology supports automatic transfer to battery during utility failure, enabling immediate continuity of service.

Deployment is suitable for 2U rack/tower form factor installations in core and consolidation racks, IDF/MDF closets, and small data centers where 120 V AC service is standard. The unit includes internal bypass, allowing continued power delivery during maintenance or service operations without disrupting attached loads. A Gigabit network card is installed in the Mini‑Slot expansion port, enabling remote monitoring, SNMP/Web alerts, and integration with Eaton’s Intelligent Power Software Suite for controlled shutdown scripting and event logging.

Communications include Ethernet via the installed network card, USB (HID), and RS‑232 serial interfaces, along with remote ON/OFF and relay contacts, facilitating integration with infrastructure monitoring and management systems. Local status and configuration are accessible via a graphical front panel display with programmable menu.

A practical deployment example is powering a core rack containing virtualized servers, SAN/NAS storage, and aggregation switches. During a utility outage or voltage instability, the online UPS supplies uninterrupted power with tight regulation and battery support, enabling orderly shutdown procedures or bridging to standby generation without service interruption. Because runtime with internal batteries is finite, extended battery modules (EBMs) may be added to increase bridge time where long outages are anticipated.

This model is not suitable for very small branch closets or desktop environments where lower‑capacity line‑interactive UPS units suffice. It also lacks modular power stages and internal maintenance bypass options found in larger enterprise UPS platforms with hot‑swap power modules, so those architectures should consider appropriately scaled UPS families.
