Centralized three-phase continuity in a rack

The M90C-2S delivers centralized three-phase protection within standard rack deployments — supporting modernization of legacy fixed-capacity UPS while simplifying service workflows and runtime scalability. Its dual-slot architecture uses one power module and one battery module in a compact 6U chassis, enabling phased runtime expansion without chassis replacement. Unlike floor-standing three-phase UPS, the rack-integrated approach brings continuity into existing rack infrastructure, in micro-data-center, secure IT, clinical-technology, edge-aggregation, and industrial-control environments.

Federal, VA & healthcare-ready

With TAA compliance, modular serviceability, and a compact rack footprint, the M90C-2S is positioned for regulated U.S. infrastructure — VA medical facilities, federal data centers and secure IT rooms, Department of Defense infrastructure, government research laboratories, and federally funded modernization programs. Its compact rack-integrated form factor supports phased deployment within existing IT and clinical-technology rooms — without electrical-room reconstruction — aligning with healthcare modernization efforts such as VA Electronic Health Record Modernization (EHRM), where clinical-system availability and procurement compliance are critical.

What the M90C-2S delivers

Rack-mounted, front and rear

Installed in a standard rack: the front (right) presents the power module with cooling fans and the per-phase LCD over the battery module; the rear (left) exposes the input and output breakers, the integral maintenance bypass and maintain switch, and the receptacle panel with its input line cord — no external bypass panel required.

The compact rack three-phase tier

The M90C platform is the compact, rack-integrated three-phase modular tier within the Xtreme Power modular ecosystem — sitting between single-phase modular and facility-scale three-phase systems. Rack-integrated platforms like the M90C are selected when continuity must deploy inside rack environments, electrical-room expansion is constrained, localized centralized protection is required, or federal procurement compliance is necessary.

Within the M90C platform: the M90C-2S (5–8 kW) is optimized for secure rack deployments and localized continuity; the M90C-6S (5–24 kW) supports higher-density aggregation and extended runtime. There is also a 400 V global sibling, the M90Ci-2S.

M90C-2S or facility-scale M90U?

Rack-integrated modular platforms such as the M90C-2S are selected when continuity must deploy within rack environments, electrical-room expansion is constrained, or federal and healthcare modernization (such as VA EHRM) calls for phased, in-rack deployment. Facility-scale modular platforms such as the M90U are selected when continuity capacity exceeds rack-deployment thresholds, centralized electrical-room deployment is preferred, or enterprise-scale load growth is anticipated.

Two configurations, 5–8 kW

Both models are 6U (17.3 × 31.5 × 10.5 in, 34 lb) with unity output power factor and a ±96 VDC (default) or ±120 VDC battery system, 4 A charging. Output is hardwired (terminal blocks) or via one optional receptacle panel per enclosure. Up to 8 battery modules are supported per power module via the optional extended battery cabinet.

Runtime by load

Estimated runtime in minutes at the base configuration (one power module and one battery module), by load. The 5 kW model is rated to 5 kW; the 8 kW model extends to 8 kW.

Estimated minutes; values vary with battery age and site conditions. Runtime extends by adding battery modules (up to 8 per power module) via the optional extended battery cabinet. For runtime sizing, contact Xtreme Power at (800) 582-4524 or sales@xpcc.com.

Where the M90C-2S is deployed

The M90C-2S is deployed where compact, compliant three-phase continuity is required — VA medical and federal data-center / secure IT rooms, Department of Defense and government research infrastructure, micro-data-centers and edge-compute aggregation, secure healthcare technology environments, and industrial control clusters — particularly in space-constrained sites and phased modernization programs such as VA EHRM.
