Xtreme Power offers two distinct approaches to three-phase UPS design: modular UPS platforms and rack-integrated UPS systems.
The M90 modular platforms, including M90C and M90U, replace traditional centralized and rack-based UPS architectures with scalable, serviceable systems. The Ai90 platform integrates UPS, batteries, bypass, and distribution into a single rack-level system optimized for high-density infrastructure.
M90 modular platforms use component-level modularity, while Ai90 applies system-level modularity at the rack level.
Both architectures are deployed across data center, telecom, healthcare, and edge environments depending on infrastructure strategy and density requirements. Many BladeUPS replacement projects begin with this architecture decision.
M90 Platform Overview
The M90 modular UPS platform includes two configurations designed for different deployment environments.
M90C modular UPS is optimized for rack-based, edge, and distributed IT environments, while M90U modular UPS supports centralized and row-based UPS systems. Both platforms use a modular architecture but are applied differently depending on system scale.
M90 vs Ai90 — At a Glance
| Category | M90C / M90U Modular UPS | Ai90 UPS |
| Architecture | Modular UPS system | Rack-integrated system |
| Deployment model | Centralized, row-based, or rack-based | Distributed, rack-level |
| Integration | UPS modules with external components | Fully integrated system |
| Scalability | Component-level modular | System-level modular per rack |
| Infrastructure | External batteries and distribution | Integrated batteries and distribution |
| Best fit | Replacement, expansion, and legacy architecture support | Modernization and high-density infrastructure |
Understanding Modularity
Both M90 and Ai90 are modular platforms, but they apply modularity differently.
M90 uses component-level modularity, where power and battery modules are installed within a centralized system, enabling incremental growth and N+1 redundancy. Ai90 uses system-level modularity, where each rack functions as a complete UPS system, allowing infrastructure to scale by adding rack-level power blocks.
Architecture and Deployment Model
M90 modular platforms use a centralized or semi-centralized architecture, with power modules and external distribution supporting multiple racks or rooms. M90C is typically deployed in distributed rack and edge environments, while M90U supports larger centralized or row-based deployments.
Ai90 consolidates UPS, batteries, bypass, and distribution into a single rack-integrated system. This enables rack-level deployment, reduces infrastructure complexity, and simplifies expansion.
Choosing the Right Architecture
Selecting between M90 modular platforms and Ai90 is an architectural decision based on deployment model, density requirements, and long-term infrastructure strategy.
Choose M90 Modular UPS When
- Replacing existing centralized UPS systems (M90U)
- Supporting row-based or data center UPS deployments (M90U)
- Deploying modular UPS in rack or edge environments (M90C)
- Maintaining current power distribution architecture
- Scaling capacity within an existing facility
Choose Ai90 Rack-Integrated UPS When
- Increasing rack power density
- Deploying high-density compute or AI infrastructure
- Reducing footprint and infrastructure complexity
- Building modular or prefabricated data center environments
M90C vs M90U Deployment Fit
| Platform | Best Fit | Typical Use Case |
| M90C | IDF, edge, telecom, rack deployments | Distributed IT and network closets |
| M90U | Data center rows, centralized UPS systems | Data center infrastructure |
Density and Footprint
M90 systems distribute UPS capacity across modular frames and external battery systems, requiring dedicated space depending on configuration.
Ai90 integrates UPS, batteries, bypass, and distribution within a compact footprint, enabling higher power density and more efficient use of rack space.
Scalability Approach
M90 platforms scale through the addition of power and battery modules within a system, supporting component-level modular growth.
Ai90 scales at the system level, with each rack functioning as a modular power block.
Runtime Strategy
M90 supports both short and extended runtime configurations through external battery systems.
Ai90 is optimized for short-duration runtime to support transition to generator-backed systems, aligning with modern data center design.
Serviceability
M90 modular architecture allows individual modules to be serviced without impacting system operation.
Ai90 simplifies service through an integrated architecture, reducing component count and improving service efficiency.
