Rack-Integrated High-Density UPS Architecture

Ai90 enables deployment of three-phase UPS protection directly within the rack, aligning power infrastructure with compute density. By integrating power conversion, battery, bypass, and distribution into a single system, Ai90 eliminates centralized UPS cabinets, reduces infrastructure complexity, and improves deployment efficiency.

This architecture allows three-phase UPS protection to be deployed at the point of use within modern high-density environments, including AI clusters, modular data centers, and industrial systems.

Ai90 UPS Overview

Ai90 is a modular online double-conversion UPS designed for environments requiring high power density within standard rack infrastructure. It delivers conditioned three-phase power directly at the rack level without reliance on centralized UPS systems.

Configuration Overview

Ai90 supports multiple voltage and capacity configurations aligned with regional infrastructure requirements.

400/230 V (3-phase, 4-wire)
480/277 V (3-phase, 4-wire)
480 V (3-phase, 3-wire)

Available models include 50 kW, 60 kW, and 70 kW configurations.

Where Ai90 Fits

Ai90 operates as the high-density platform within the Xtreme Power rack-integrated UPS architecture. It is typically deployed in environments requiring high-capacity three-phase UPS protection within a rack, including AI infrastructure, high-density compute, and modular data center designs. It is selected when centralized UPS systems are replaced with distributed rack-level power architectures or when power density exceeds the range of smaller modular systems.

Within the Xtreme Power architecture:

M90Ci-2S → 10 kW compact rack-integrated modular UPS
M90Ci-6S → scalable modular platform
Ai90 → 50–70 kW high-density rack-integrated UPS (this system)

This creates a scalable path from compact rack-level three-phase UPS deployment to high-density rack-integrated power infrastructure.

Rack Power Integration and Distribution

Ai90 integrates output distribution directly within the UPS system, enabling simplified connection to downstream rack power systems. It supports hardwired output or configurable distribution options aligned with high-density rack deployments.

Ai90 vs Centralized UPS Architecture

Traditional UPS systems are centralized, requiring dedicated electrical rooms and large distribution infrastructure. Ai90 delivers three-phase power in a rack-integrated architecture, enabling localized power protection, reduced cabling complexity, simplified expansion, and improved deployment speed.

Electrical Integration

Ai90 is designed for permanent installation with hardwired input and output connections. Integrated maintenance bypass supports safe service operation, while modular internal architecture simplifies maintenance and system access.

Rack Deployment and Installation

Ai90 is designed for installation within standard equipment racks. The system is delivered in modular sections for simplified transport and installation, then integrated within the rack using internal bus connections. This approach supports faster deployment compared to traditional floor-standing UPS systems.

Runtime Strategy

Ai90 is optimized for short-duration runtime with internal batteries, providing up to 3.7 minutes of ride-through for transition to generator-backed systems. Extended runtime is available through external battery cabinets (Ai90 EBC-4).

When to Use Ai90

Ai90 is typically selected when high-density three-phase power is required within a rack environment, particularly in:

AI and GPU compute infrastructure
High-density data center racks
Modular or prefabricated data centers
Distributed industrial systems

It is well suited for environments transitioning from centralized UPS systems to distributed rack-level architectures.

Replace Eaton, Vertiv, and BladeUPS Systems

Ai90 is commonly deployed as a replacement for large centralized UPS systems from Eaton, Vertiv, and similar manufacturers. It enables modernization by shifting from facility-level UPS architecture to rack-integrated power systems, improving scalability, density, and deployment flexibility. It is also a strong replacement for Eaton BladeUPS systems, enabling migration from centralized legacy UPS architecture to distributed rack-integrated infrastructure aligned with modern high-density environments.
