About the Eaton 9395X UPS 250kW
The Eaton 9395X UPS 250kW is a large-scale, three-phase online double-conversion uninterruptible power system purpose-built for the demanding power profiles of hyperscale cloud infrastructure, AI/ML compute clusters, and mission-critical enterprise data centers. Launched in Q2 2025, the 9395X builds upon Eaton's proven 9395 platform with a next-generation power module architecture that delivers exceptionally high power density in a compact footprint, reducing the capital and operational burden of physical data center space. The unit supports both traditional VRLA battery strings and modern lithium-ion battery cabinets, enabling facilities teams to tailor runtime, weight, and lifecycle economics to their specific operational requirements.
Ideal for
- Hyperscale AI training clusters requiring uninterrupted, high-quality power delivery to GPU and accelerator nodes
- Colocation data centers needing scalable, modular UPS capacity to serve multi-tenant power domains up to and beyond 250kW per unit
- Edge and regional data centers consolidating legacy parallel UPS strings into a single high-efficiency 250kW system
- Financial services trading infrastructure demanding sub-millisecond transfer times and continuous availability under grid anomalies
- Healthcare and life-sciences HPC environments requiring IEC 62040-3 Class 1 (VFI) isolation from utility disturbances
- Industrial and manufacturing automation facilities with sensitive servo and robotics control systems requiring pure sine wave output
