Eaton 5P1150IRG2 1.15 kVA / 1150 W Gen2 Rack UPS

PRODUCT OVERVIEW

Product Purpose and Core Architecture

The Eaton 5P1150IRG2 is a rack‑mount, line‑interactive UPS with a rated capacity of 1150 VA / 920 W, engineered to protect mission‑critical IT equipment such as rack servers, network switches, storage systems, and virtualization hosts. It sits in Eaton’s 5P Gen2 family, which balances power quality, efficiency, and scalability for small‑ to mid‑sized enterprise environments. Its 1 U rack form factor and high energy efficiency (98.2 %) make it suited for dense rack deployments where power protection must be robust yet space‑conscious. The unit complies with major safety and performance standards—IEC/EN 62040‑1/‑2/‑3, UL 1778, CSA, CE, UKCA, and others—ensuring broad regulatory acceptance across regions.

Electrical Architecture and Power Conditioning

This UPS uses line‑interactive topology, a design that actively regulates voltage without switching to battery power for common transient fluctuations, thereby reducing unnecessary battery cycling and improving overall durability. It delivers a true sine wave output, which is essential for sensitive IT loads, especially those with active PFC (power factor corrected) power supplies. The output power factor of 0.8 indicates that the unit can supply 920 W of real power from its 1150 VA rating, aligning with typical IT equipment power draw characteristics. The input accepts a wide voltage range (adjustable between 150 V and 294 V), accommodating unstable mains conditions without tripping to battery mode prematurely.

Battery System and Runtime Details

Internally, the 5P1150IRG2 is fitted with four user‑replaceable sealed lead‑acid (VRLA) batteries (6 V/9 Ah each), with hot‑swappable capability that enables battery replacement without shutting down connected devices. Eaton’s Advanced Battery Management (ABM+) technology dynamically adjusts charging algorithm and conducts periodic battery tests to extend life and improve prediction accuracy. Typically, at half load, the UPS provides a useful buffer (~12.5 minutes) to bridge short outages or facilitate graceful shutdowns. Importantly, external battery cabinets are not supported on this model, so runtime is limited to the internal battery configuration.

Connectivity, Interface, and Systems Integration

For monitoring and control, the 5P1150IRG2 includes a multilingual graphical LCD display that provides real‑time status on input/output voltages, load percentage, battery condition, and operating mode. It also features USB (HID‑compliant) and RS‑232 serial ports, as well as dry contacts and a mini terminal block for remote On/Off and emergency power off (EPO) integration. A single expansion slot allows installation of optional communication cards (e.g., network management or industrial interface modules) for SNMP or advanced network‑based monitoring. The unit integrates with Eaton’s Brightlayer Software suite, supporting automated shutdowns, alerting, and telemetry collection within virtualized and mixed OS environments (including VMware, Hyper‑V, Citrix, and Redhat)
