Scalable, modular power for mission-critical availability

The M90U-140 protects critical data and equipment while supplying clean, network-grade power. It can be configured with fully redundant power and battery modules; should one module fail, the remaining modules smoothly take over the load. Power modules are independent and hot-swappable without risk to the critical load — so capacity and redundancy both scale over time within a single frame.

Enterprise modular UPS architecture

The M90U-140 enables large-scale capacity within a single modular system. Redundancy is implemented in an N+1 configuration without requiring parallel UPS systems, and the platform supports long-term expansion while maintaining centralized continuity, modular serviceability, and simplified lifecycle planning. Compared with monolithic multi-cabinet systems at this scale, the modular approach lets both capacity and redundancy scale over time while improving serviceability and reducing system-replacement requirements.

What the M90U-140 delivers

Model selection guide

The frame holds up to eight power modules. The 20 kW module line is shown below; a 15 kW module line is also available. Unity power factor means the kVA and kW ratings are equal.

The frame accepts up to eight power modules — up to seven active, plus a redundant module for N+1. With 20 kW modules the system reaches 140 kW (7 × 20) or 140 kW with N+1 (the eighth module is the redundant spare); with 15 kW modules it reaches 105 kW (7 × 15) or 105 kW with N+1. Maximum system capacity is 140 kW — the eighth slot adds redundancy, not capacity. Charge current scales with the populated module count (8–56 A).

Modular battery strings built for serviceability

Runtime is delivered by the matching M90-BC modular battery enclosure — a design many customers choose specifically for its serviceability and compact footprint. Battery is organized as up to eight independent strings, each with its own 100 A breaker, so an individual string can be isolated for service or replacement without taking down the others. Each string is built from four hot-swappable battery modules (up to 32 modules total), and the whole system fits a notably small footprint — an industry-leading footprint that saves up to 40% of floorspace versus comparable platforms, counting batteries and maintenance bypass.

Battery runtimes

Runtime scales with the number of installed battery modules. Typical runtimes (minutes) for the M90-BC enclosure across system load:

System load shown in kVA across the top; runtimes are typical (minutes) and vary with battery condition, age, cycles, and ambient temperature. Battery life is reduced above 30°C and capacity derates above 30°C and 5,200 ft. Contact Xtreme Power at (800) 582-4524 or sales@xpcc.com for runtime sizing.

The enterprise member of the M90U family

M90U-140 is the enterprise-scale platform within the M90U family — for centralized deployments needing capacity and redundancy beyond the high-density M90U-80. The entry M90U covers 15–60 kW, the M90U-80 covers 15–80 kW in a single integrated cabinet, and the M90LU offers an external-battery extended-runtime sibling. For lithium, the Li90 is an integrated lithium facility UPS.

Replace legacy and aging modular UPS

The M90U-140 is commonly deployed to replace large legacy and aging modular platforms — including the APC Symmetra PX, Eaton 93PM, and Vertiv Liebert EXM — in data center modernization and capacity expansion, replacement of aging centralized UPS, infrastructure needing scalable redundancy and runtime flexibility, and consolidation of multiple UPS into one modular platform.

Where the M90U-140 is deployed

M90U-140 is deployed across enterprise-scale environments — data centers and large electrical rooms, healthcare and campus facilities, telecommunications core infrastructure, and industrial and process systems.

Approvals and warranty

The M90U-140 carries UL-1778, cUL, FCC Class A, and RoHS, and is TAA compliant on select models — confirm TAA eligibility for the specific model and configuration when a regulated procurement requires it. It is backed by a 2-year electronics and 2-year battery warranty (USA and Canada).
