Eaton SUINT3000LCD2U – Online Double‑Conversion UPS 3000 VA 2700 W

Overview

The Eaton SUINT3000LCD2U is a rack/tower online double‑conversion uninterruptible power supply (UPS) engineered to provide continuous conditioned AC power and battery backup for critical IT infrastructure loads. It is deployed by data center engineers, network architects, and facilities teams in environments where utility power fluctuations, brownouts, and outages must not impact servers, storage systems, network switches, and other sensitive electronics. The online double‑conversion topology continuously regenerates the output waveform, ensuring a true sine‑wave supply and zero transfer time when transitioning to battery support.

This model delivers 3000 VA / 2700 W output with a 0.9 power factor, suitable for a full rack of mid‑range servers, virtualization hosts, and connected infrastructure. It includes (8) IEC C13 and (2) IEC C19 outlets, providing mixed receptacle types to support a broad range of rack equipment without additional distribution hardware. Internal batteries are hot‑swappable and runtime can be extended using optional external battery modules (EBMs) for prolonged outages or generator transition.

Deployment is typically in a 2U rack/tower form factor, with included rack mount kit and support for shallow 19‑inch server cabinets or small equipment rooms where full UPS performance is needed without consuming excessive space. The unit’s front‑panel LCD delivers real‑time status information — including load, battery condition, and input/output metrics — enhancing on‑site diagnostics.

Communications include USB (HID) and RS‑232 serial interfaces for local monitoring and integration with Eaton’s management tools, along with an expansion port for optional network management cards (e.g., SNMP/Web) for remote monitoring and alerting. Internal bypass ensures load continuity during internal servicing.

A practical deployment example is protecting a consolidation rack containing virtualization servers, SAN/NAS storage, and core network switches in a small data center or edge facility. During utility disturbances, the online double‑conversion design maintains uninterrupted, regulated power while optional EBMs extend runtime to enable orderly shutdowns or facilitate failsafe handoffs to standby generators.

This model is not suitable for simple desktop or shallow closet scenarios where lower‑capacity line‑interactive UPS units suffice, nor for very high‑availability data halls where modular UPS architectures with hot‑swappable power modules and service bypass cabinets are required.
