Modular Facility UPS Architecture

M90U defines the category of modular three-phase UPS systems for scalable facility infrastructure. The platform enables capacity to be built incrementally using modular power blocks. Additional modules can be installed as load requirements increase, while redundancy can be implemented within the same system using N+1 configuration.

This architecture allows infrastructure to scale without system replacement or oversizing at initial deployment, supporting long-term capacity planning and efficient capital allocation.

Where M90U Fits

M90U operates as the entry modular facility UPS platform within centralized infrastructure environments. Within the Xtreme Power architecture:

• P91 / J90 → rack-level UPS systems
• Li90 → integrated lithium facility UPS
• M90U → modular UPS with internal batteries (this platform)
• M90LU → modular UPS with external battery architecture
• M90U-80 / M90U-140 → higher-capacity modular systems

M90U is typically deployed in electrical rooms where load aggregation exceeds the capability of rack-based UPS systems and centralized UPS architecture is required.

Key Advantages of M90U

M90U is engineered for facilities where scalability, redundancy, and centralized power architecture are primary design priorities.

• Modular scalability from 15 kW to 60 kW
• N+1 redundancy within a single system
• Internal battery integration for compact deployment
• Phased capacity expansion aligned with infrastructure growth
• Improved lifecycle flexibility compared to fixed-capacity UPS systems
• Centralized power architecture replacing distributed UPS systems

M90U vs Traditional Fixed-Capacity UPS

Traditional UPS systems are deployed at a fixed capacity and are often oversized to accommodate future growth. M90U enables both capacity and redundancy to be scaled within a single system, reducing the need for system replacement and allowing infrastructure to evolve as load requirements increase.

M90U vs External Battery Modular UPS (M90LU)

M90U and M90LU share the same modular UPS platform but differ in battery architecture.

• M90U → internal batteries, compact deployment and standard runtime
• M90LU → external batteries, extended runtime and flexible battery design

M90U is typically selected when internal battery runtime is sufficient and a simplified, integrated system is preferred.

M90U vs Lithium UPS Platforms

M90U represents a modular VRLA-based approach optimized for scalability and phased infrastructure growth. Lithium UPS platforms such as Li90 prioritize reduced maintenance, integrated battery design, and higher energy density. M90U is typically selected when modular expansion, redundancy, and long-term capacity growth are the primary drivers.

Capacity Guidance

Capacity is defined by module configuration and infrastructure growth strategy. Systems typically deploy at 15–20 kW for initial installations, scale to 30–40 kW as infrastructure expands, and reach 50–60 kW in fully populated configurations. N+1 redundancy can be implemented within the same system to support higher availability requirements.
