Modular Rack-Integrated UPS Platform vs Floor-Standing UPS Architecture


The Xtreme Power Ai90 platform is a high-density, modular rack-integrated UPS system engineered for modern digital infrastructure requiring scalable, space-efficient power protection in the 40–80kW range.

Engineers evaluating the Schneider Electric Galaxy VS platform often seek UPS solutions that reduce infrastructure footprint, simplify deployment, and support higher rack power density.

This comparison focuses on 480V and 400V systems in the 40–80kW range, where both platforms support internal battery configurations for short-duration runtime.

While Galaxy VS provides a modular UPS platform within a floor-standing cabinet architecture, the Ai90 platform delivers a modular rack-level UPS solution optimized for distributed infrastructure, generator-backed systems, and high-density deployments.

Rack-Level vs Floor-Standing UPS Architecture

The Ai90 platform enables UPS deployment directly within the rack, allowing power protection to scale with compute infrastructure. This reduces cabling complexity, eliminates dedicated UPS space, and accelerates deployment timelines.

The Galaxy VS platform is designed as a modular UPS system requiring a floor-standing cabinet architecture, even when internal batteries are included.


Power Density and Infrastructure Efficiency

Ai90 delivers more than 5kW per U within a 13U footprint, enabling significantly higher rack utilization.

Ai90 occupies approximately 70% less physical volume than comparable Galaxy VS configurations, enabling deployment directly within standard rack infrastructure rather than requiring dedicated floor space.

Galaxy VS systems occupy full-height cabinets and are not designed for rack-level density.


Deployment Model

Ai90 is delivered as a two-section rack system:

• 5U UPS section
• 8U battery section

Installed directly into a standard rack and connected via busbars during commissioning.

Galaxy VS systems are deployed as floor-standing cabinets requiring facility-level planning and supporting infrastructure.


Ideal Applications

• AI and high-density compute racks
• High-performance computing (HPC)
• Edge data centers
• Industrial automation systems
• Healthcare and laboratory environments
• Telecommunications infrastructure


Plan Your Rack-Level Power Architecture

Engineers evaluating UPS platforms at this scale are typically balancing density, deployment model, and infrastructure complexity.

Xtreme Power Conversion supports system design, runtime planning, and specification development for rack-level UPS deployments.
