PRODUCT OVERVIEW
High-Performance Online UPS Protection
The Eaton 9SX11KIRT4UG2 is a high-capacity, online double-conversion uninterruptible power supply (UPS) designed to deliver robust, clean, and highly reliable power for mission-critical systems. It offers 11 kVA / 11 kW output with a power factor of 1.0, meaning it supports heavy and complex electrical loads without derating. This model is ideal for data centres, server rooms, telecom equipment, and industrial applications that cannot tolerate power disturbances or downtime. The unit is available in a rack-mountable 4U form factor with tower capability, giving flexibility during installation.
Design and Compliance – Industrial-Grade Build
Engineered for demanding environments, the Eaton 9SX11KIRT4UG2 complies with key global standards, including IEC/EN 62040-1, -2, -3, ENERGY STAR, CE, cULus, UKCA, and other regional safety and EMC directives. This certification suite illustrates that the product meets stringent electrical safety, electromagnetic compatibility, and energy efficiency criteria, enabling deployment in commercial, enterprise, and regulated sectors. The unit’s physical dimensions support standard 19-inch rack systems, and it weighs approximately 78.8 kg.
Battery System – Hot-Swappable and Expandable Runtime
At its core, the Eaton 9SX11KIRT4UG2 uses a sealed lead-acid battery array with ABM+™ predictive charging and deep-discharge protection to optimize battery longevity and health. The internal battery configuration includes 20 cells and supports hot-swappable replacement without interrupting UPS operation. Additionally, extended battery modules (EBMs) can be added to significantly increase runtime for longer outages or higher loads. This intelligent battery management ensures both reliability and lower operational costs over the long term.
Electrical Performance and Output Quality
This UPS delivers pure sine wave output across its multiple receptacles—specifically (8) IEC C13 and (4) IEC C19 outlets, plus hardwired connections—suitable for a wide variety of critical IT and telecom equipment. The online double-conversion topology continuously regenerates power, eliminating surges, noise, and interruptions. The input voltage tolerance range spans 100 – 276 V (with derating), while output voltage can be configured across 200/208/220/230/240 V, maintaining high stability and low total harmonic distortion even under linear loads.
