Rack-Integrated UPS Architecture for Distributed Power Deployment
Rack-integrated UPS systems represent a shift from centralized electrical infrastructure to distributed, rack-level power architecture aligned with modern compute deployments.
Modern data center environments are increasingly built around high-density rack deployments requiring scalable, distributed power architecture.
System Definition
The Ai90 platform is a rack-integrated modular UPS architecture designed to deliver three-phase power protection directly within the equipment rack, typically supporting system capacities in the 50–70kW range depending on configuration.
Systems are designed for common data center voltages including 400/230V and 480/277V, aligning with modern infrastructure deployment standards.
This approach aligns power infrastructure with modern compute deployment models, enabling UPS systems to be installed alongside IT equipment rather than in centralized electrical rooms.
Architecture Concept
Ai90 integrates power conversion, battery systems, maintenance bypass, and distribution within a unified rack-mounted system.
This contrasts with traditional UPS deployments where power protection is installed as a separate, floor-standing system and connected through facility-level distribution.
By consolidating these elements into the rack, Ai90 reduces infrastructure dependency and simplifies system design.
Key Engineering Characteristics
• Rack-integrated three-phase UPS architecture
• Modular power and battery system design
• Integrated maintenance bypass and distribution
• Designed for installation within standard equipment racks
• Internal system interconnection using busbar architecture
Why Rack-Level UPS Architecture
Infrastructure design is increasingly driven by:
• higher compute density
• distributed deployment models
• prefabricated and modular data center construction
• reduced installation timelines
Rack-integrated UPS architecture enables power protection to scale with compute infrastructure rather than being constrained by centralized electrical design.
System Integration Model
Ai90 is designed for installation within standard equipment racks and integrates into typical rack deployment workflows.
The system is delivered in multiple rack-mount sections and assembled within the rack using internal busbar connections.
This model supports:
• standardized installation practices
• simplified transportation and handling
• reduced on-site integration complexity
• alignment with prefabricated rack solutions
Deployment Example
Ai90 deployed within a standard rack integrates UPS, battery, maintenance
bypass, and distribution, enabling rack-level three-phase power
protection aligned with high-density infrastructure.
In a high-density rack deployment, Ai90 can be installed directly within the same rack as compute and network equipment, providing localized three-phase power protection without reliance on centralized UPS infrastructure.
Power is delivered to the rack, and Ai90 supports downstream loads through integrated distribution, reducing the need for extended branch circuits and external UPS cabinets.
This approach enables:
• rack-level power protection aligned with compute density
• reduced installation complexity and cabling requirements
• faster deployment through pre-integrated rack solutions
• simplified expansion as additional racks are deployed
Runtime Philosophy
Ai90 is designed around short-duration internal runtime with the ability to extend runtime using external battery cabinets.
This approach aligns with generator-backed infrastructure strategies where UPS systems provide ride-through during power transitions rather than extended standalone operation.
Typical Deployment Environments
• high-density compute and AI infrastructure
• edge data centers and distributed IT environments
• prefabricated and modular data center deployments
• colocation and multi-tenant environments
• industrial and infrastructure applications requiring localized power protection
Infrastructure Alignment
Rack-integrated UPS systems operate as part of a broader infrastructure architecture that includes power distribution, monitoring, and system-level design considerations.

Position Within Infrastructure
Ai90 is one implementation of rack-integrated UPS architecture designed for distributed infrastructure environments.
Other UPS architectures serve different roles:
• centralized UPS systems for facility-level protection
• modular UPS systems for scalable electrical infrastructure
• cabinet-based UPS systems for integrated room-level deployments
Selecting the appropriate architecture depends on deployment model, scalability requirements, and facility design constraints.
