Ai90 Rack-Integrated UPS (50–70 kW) | High-Density 3-Phase UPS System

High-density three-phase protection, at the rack

The Ai90 defines the category of high-density rack-integrated three-phase UPS systems. It delivers conditioned three-phase power directly at the rack level — without reliance on centralized UPS cabinets — consolidating power conversion, battery energy storage, maintenance bypass, and output distribution into a unified rack architecture. This supports resilient deployment across high-density compute, edge infrastructure, industrial systems, healthcare technology, and research environments where space efficiency and serviceability are critical.

Power protection aligned with compute density

Ai90 enables three-phase UPS protection to be deployed within the rack, aligning power infrastructure with compute density. By integrating power conversion, battery, bypass, and distribution into a single 13U system, it eliminates centralized UPS cabinets, reduces infrastructure complexity, and improves deployment efficiency — achieving over 5 kW per U in 480V systems. The platform ships in modular sections (a 5U UPS section and an 8U battery section, busbar-connected) for simplified transport and faster installation than floor-standing UPS.

What the Ai90 delivers

Voltage and capacity configurations

Ai90 supports multiple voltage and capacity configurations aligned with regional infrastructure requirements. The 480V configurations reach 70 kW; the 400/230V configuration is offered to 60 kW.

All models are 13U rack-integrated, unity power factor, online double-conversion, with integrated battery, bypass, and distribution. Output distribution modules (one per system): A = (4)×63A, B = (2)×100A, C = (2)×125A 3-pole breakers; hardwired or factory pigtails (NEMA / IEC 60309). Input voltage range +15% / −20% at 100% load; 50/60 Hz.

Runtime by load and battery configuration

Approximate runtime in minutes by load, from internal batteries (two strings) through one to seven Ai90-EBC4 external battery cabinets. The Ai90 is optimized for short-duration ride-through to generator transfer, with external cabinets extending runtime as needed.

Runtimes are approximate and vary with battery age and site conditions. Internal ride-through is up to 3.7 minutes at 50 kW (less at higher loads); each Ai90-EBC4 is a 4U rack cabinet with (4) battery modules and an integrated breaker.

The high-density tier of the rack-integrated family

Ai90 is the high-density platform within the Xtreme Power rack-integrated UPS architecture — the step up from compact rack-level modular systems to high-capacity rack-integrated power. It is selected when centralized UPS systems are replaced with distributed rack-level architectures, or when power density exceeds the range of smaller modular systems.

Need higher-capacity 480V protection? See the X90-2s. For system design context, see the rack power architecture guide.

Same protection, floor-standing: the X90-1S

The Ai90 puts 50–70 kW of 480V three-phase protection inside the rack. When the UPS belongs on the floor beside the load instead of in the rack, the X90-1S delivers the same 50–70 kW 480V single-module architecture — power module, batteries, and integrated maintenance bypass — as a self-contained, tower-style floor-standing cabinet just 23.6″ wide. Same protection, two form factors: the Ai90 rack-integrated in 13U, or the X90-1S as a free-standing cabinet beside the load.

Distributed power, not a central cabinet

Traditional UPS systems are centralized, requiring dedicated electrical rooms and large distribution infrastructure. The Ai90 delivers three-phase power in a rack-integrated architecture — enabling localized power protection, reduced cabling complexity, simplified expansion, and faster deployment. It is also a strong replacement for end-of-life Eaton BladeUPS systems, enabling migration from centralized legacy architecture to distributed rack-integrated infrastructure.

Where the Ai90 is deployed

The Ai90 is deployed where high-density three-phase power is required within a rack environment — AI and GPU compute clusters, high-density data center racks, edge and modular/prefabricated data centers, IDF and MDF environments, telecommunications infrastructure, industrial and automation systems, and healthcare and laboratory systems. It is especially suited to environments transitioning from centralized UPS to distributed rack-level architectures.

TAA-compliant rack power

The Ai90 is TAA compliant alongside UL, CE, and RoHS — supporting regulated data center, government, and enterprise deployments requiring Trade Agreements Act compliance.
