The Eaton BladeUPS platform was widely deployed in 400/230 V data center environments, providing modular three-phase UPS protection within a rack-based system. With BladeUPS now discontinued, organizations are evaluating replacement strategies aligned with modern infrastructure design.

The Ai90 UPS from Xtreme Power introduces a different architectural approach by integrating UPS, batteries, bypass, and distribution into a single rack-level system. Xtreme Power supports both modular UPS replacements and rack-integrated UPS architectures, allowing organizations to modernize at their own pace.

Ai90 vs Eaton BladeUPS 400V At a Glance

Category	Ai90	Eaton BladeUPS
Platform status	Current	Discontinued
Architecture	Rack-integrated	Modular in rack
Rack space 60 kW	13U	Approximately 42U
Power density	Greater than 5 kW per U	Approximately 1.4 kW per U
Integration	Fully integrated	Multi-component
Deployment model	Distributed	Centralized or semi-centralized

Architecture and Deployment Model

BladeUPS systems were designed around modular 12 kW UPS units installed within a rack enclosure, scaling up to approximately 60 kW with N+1 redundancy. While rack-mounted, these systems typically operated as centralized or semi-centralized UPS architectures, requiring external distribution and integration into facility-level power infrastructure.

Ai90 consolidates UPS, batteries, maintenance bypass, and distribution into a single integrated system deployed directly within the rack. This enables a shift to rack-level power infrastructure, reducing system complexity and simplifying deployment.

Rack Space and System Density

BladeUPS relied on multiple modular components within a rack system, requiring coordination across power modules, batteries, and bypass assemblies. Ai90 simplifies service through an integrated architecture, reducing component count and improving overall service efficiency.

BladeUPS Replacement vs Architecture Redesign

BladeUPS replacement strategies typically fall into two categories.

Modular Replacement Approach

Best for maintaining existing UPS architecture.

Replaces BladeUPS with similar modular systems
Preserves centralized or rack-based UPS design
Minimizes changes to existing infrastructure

Platforms:

M90C modular UPS

M90U modular UPS

M90Ci modular UPS

Rack-Integrated Architecture Approach

Best for modernization and high-density environments.

Deploys UPS directly at the rack level
Reduces infrastructure and cabling complexity
Enables higher rack power density

Platform:

Ai90 rack-integrated UPS

Ai90 is typically selected when the goal is infrastructure modernization rather than direct equipment replacement.

Runtime Strategy

Ai90 is optimized for short-duration runtime, providing approximately 3.7 minutes of internal runtime to support transition to generator-backed systems. This aligns with modern Tier III and Tier IV data center designs where UPS systems provide ride-through rather than extended standalone runtime.

Serviceability

BladeUPS relied on multiple modular components within a rack system. Ai90 simplifies service through an integrated architecture, reducing component count and improving service efficiency.
