Eaton 9PX3000GRT‑L – Online UPS 3000 VA 2700 W 208 V

Overview

The Eaton 9PX3000GRT‑L is a rack‑mountable online double‑conversion uninterruptible power supply (UPS) designed to provide conditioned AC power and battery backup for critical 208 V infrastructure loads. It is deployed by IT infrastructure engineers, data center technicians, and facilities teams to maintain uptime for servers, storage arrays, network switches, and virtualization hosts, isolating connected equipment from utility disturbances and brownouts while delivering tight voltage and frequency regulation. The online topology actively rectifies incoming power and regenerates it, ensuring clean output without reliance on the mains waveform.

The UPS has a 3000 VA / 2700 W capacity at 208 V nominal output with true sine‑wave output and ±1 % steady‑state voltage regulation, supporting higher‑density rack loads typical of core consolidation and enterprise environments. Internal lithium‑ion batteries are managed by an integrated battery management system (BMS) and are hot‑swappable, with support for up to four extended battery modules (EBMs) to increase runtime for extended utility outages or to bridge to standby generator operation.

Deployment is in a 2U rack/tower form factor, including a 4‑post rail kit for standard 19‑inch enclosures, making it suitable for core racks, medium data halls, and IDF/MDF consolidation zones where 208 V distribution is standard. The unit features eight IEC C13 and two IEC C19 output receptacles for mixed IT loads. Communications include built‑in USB (HID) and RS‑232, and a Mini‑Slot expansion port supports optional Gigabit network, Modbus, and relay cards for remote monitoring, event logging, and integration with Eaton’s Intelligent Power Software Suite.

A typical deployment example is powering a consolidation rack with rack servers, SAN storage, and upstream network switches. During utility power loss or voltage excursions, the online double‑conversion topology maintains stable output, and extended battery modules provide additional runtime to allow orderly shutdown or handoff to standby generation. This helps avoid data corruption and service disruption in critical compute and storage clusters.

This UPS is not suitable for small branch closets, desktop workstations, or environments where lower‑capacity line‑interactive UPS models with basic battery support suffice. It also does not include integrated maintenance bypass; separate bypass or distribution infrastructure should be considered for high‑availability topologies requiring hot serviceability.
