Eaton 9PX 11000VA 10U Online UPS

The Eaton 9PX 11000VA 10U Online UPS (model 9PX11KSP) is a double-conversion, true online uninterruptible power supply engineered for continuous protection of critical IT infrastructure in server rooms, network closets, and small-to-medium data centers. Operating at a unity (1.0) power factor, the 9PX 11kVA delivers up to 10,000 watts of real power output, ensuring that the full VA rating translates directly into usable wattage for high-density compute loads. The double-conversion topology completely isolates connected equipment from raw utility power at all times, regenerating a clean, stable sine wave output and providing zero transfer time during input power failures.

A defining feature of the 9PX platform is Eaton's Advanced Battery Management (ABM) technology, which replaces conventional constant-float charging with a three-stage charging algorithm. ABM monitors battery state in real time, reducing battery operating temperature and extending service life by up to 50% compared to traditional charging methods. The unit occupies 10U of standard 19-inch rack space and supports hot-swappable batteries, enabling maintenance without powering down connected loads. The 9PX11KSP also incorporates Eaton's Energy Saver System (ESS) mode, which can achieve efficiency levels above 95% by intelligently switching to high-efficiency bypass when input power quality permits, while retaining the ability to revert to full double-conversion instantly.

Connectivity and management are addressed through a standard RS-232 and USB interface, with an available network management card slot supporting Eaton's Gigabit Network Card (Intelligent Power Protector) for SNMP, Modbus, and web-based remote monitoring. The unit is compatible with Eaton's Intelligent Power Manager (IPM) software for enterprise-wide UPS fleet oversight, automated graceful shutdown of virtualized environments, and integration with hypervisor platforms including VMware, Microsoft Hyper-V, and Nutanix. Output is delivered via hardwire terminals, appropriate for permanent rack or room-level distribution installations at this power class.

Ideal for

• Providing continuously conditioned power to high-density blade server chassis and rack-mounted compute clusters in enterprise server rooms
• Protecting storage area network (SAN) arrays and NAS enclosures where ungraceful shutdowns risk data corruption or RAID degradation
• Supplying clean, regulated power to network core switching and routing infrastructure in telecommunications or campus data closets
• Supporting virtualization hosts running VMware vSphere or Microsoft Hyper-V, with software integration for automated graceful VM migration and shutdown on extended outages
• Acting as the primary UPS layer for small colocation suites or edge data center nodes where generator transfer time cannot be tolerated
• Replacing aging legacy UPS units in existing 19-inch rack infrastructure where space efficiency, battery longevity, and energy efficiency are operational priorities
