Eaton 9PXM 4000VA 3600W Split-Phase Power Module – Scalable Backup Power for 9PXM UPS Systems

The Eaton 9PXM 4000VA 3600W Split-Phase Power Module is a purpose-built expansion accessory designed to transform your Eaton 9PXM UPS into a scalable, resilient backbone for critical workloads. This plug-and-play power module adds capacity and redundancy where you need it most, giving data centers, IT closets, and remote offices the flexibility to grow without replacing the entire UPS. With support for multiple split-phase voltage configurations, hardwired input/output, and government-grade reliability (TAA-compliant), this module is ideal for environments where uptime is non-negotiable and space is at a premium. Its modular design makes it easy to expand capacity in steps as your load increases, while preserving operational efficiency and simplicity in management. The 9PXM 4000VA module is crafted to integrate seamlessly with existing Eaton UPS ecosystems, reducing commissioning time and enabling quicker disaster recovery readiness. When you depend on steady electrical power to protect servers, networking gear, storage appliances, and virtualization platforms, this power module helps you maintain continuous service with fewer interruptions and simplified upgrades.

• Flexible power scaling and modular redundancy: This power module is engineered to slot into your existing Eaton 9PXM UPS chassis, letting you scale backup capacity in line with demand. By adding one or more modules, you can increase total available VA and create redundancy paths that minimize single-point failures. The modular approach supports growth trajectories—from modest to peak loads—without the downtime or replacement costs associated with overhauling the entire UPS system. In practice, this means you can protect more servers, virtual machines, and storage arrays while maintaining predictable performance during outages and during routine maintenance windows.
• Multivoltage operation for global compatibility: The 9PXM split-phase power module is designed to accommodate a diverse set of power environments. With configurations spanning 110/120V, 120/208V, 120/240V, and 127/220V, it aligns with regional utility standards and data center wiring schemes. This versatility reduces the complexity of cross-site deployments and simplifies fleet-wide UPS management. Operators can deploy the same module in locations with different electrical ecosystems, ensuring consistent behavior and protection for critical loads regardless of geography.
• Plug-and-play installation with hot-swappable expansion: The module is built for rapid deployment and minimal downtime. Its plug-and-play characteristics allow technicians to install it quickly within compatible 9PXM UPS units. Hot-swappable design means you can expand capacity or adjust redundancy without powering down the entire system, preserving uptime for mission-critical applications. Comprehensive installation guidelines ensure secure rack mounting, proper cable routing, and straightforward integration with existing UPS management software, keeping project timelines on track and operational risk low.
• Rugged build and compliance for demanding environments: The Eaton 9PXM 4000VA Split-Phase Power Module is constructed to withstand the rigors of data centers, server rooms, and edge locations. Its hardened hardware, designed for continuous operation in variable ambient conditions, is complemented by government procurement readiness through TAA compliance. This combination of durability and compliance makes it suitable for enterprise deployments, federal projects, and any environment where reliable power protection is essential and procurement standards demand traceability.
• Efficient protection and monitoring for critical workloads: Beyond simply supplying power, the module provides robust protection features and easy monitoring for uptime optimization. It supports advanced overcurrent, short-circuit, and fault-isolation mechanisms to shield connected equipment from power disturbances. When integrated with Eaton’s monitoring tools and UPS software, you gain visibility into load levels, runtime estimates, and health diagnostics, empowering proactive maintenance and informed capacity planning. This focus on reliability translates into fewer surprise outages and smoother disaster recovery testing.
