M90C-2S – Compact Modular Rack Three-Phase UPS

5kVA / 8kVA

208/120 VAC Three-Phase

High-efficiency modular UPS with maintenance bypass, optional receptacle panels, and TAA compliance for continuous power in IT and industrial environments.

M90C-2S Rack-Integrated Infrastructure Power Platform

5–8 kW | 208 / 120 V Three-Phase | TAA Compliant

The Xtreme Power Conversion M90C-2S is a compact modular rack-integrated three-phase UPS designed to deliver secure, scalable infrastructure continuity in federal, healthcare, enterprise IT, and industrial environments where space constraints and procurement compliance are critical.

This architecture enables centralized three-phase protection within standard rack deployments, supporting modernization of legacy fixed-capacity UPS systems while simplifying service workflows and runtime scalability.

Federal & VA Infrastructure Continuity Platform

The M90C-2S is widely deployed across regulated U.S. infrastructure due to its TAA compliance, modular serviceability, and compact rack footprint.

Typical deployment environments include:

  • VA medical facilities
  • federal data centers and secure IT rooms
  • Department of Defense infrastructure
  • government research laboratories
  • federally funded modernization programs
  • secure healthcare technology environments
  • VA Electronic Health Record Modernization (EHRM) infrastructure initiatives

Supporting VA Electronic Health Record Modernization (EHRM)

The M90C-2S is frequently deployed in support of VA Electronic Health Record Modernization (EHRM) initiatives, where clinical system availability, infrastructure resilience, and procurement compliance are critical.

Compact modular rack-integrated UPS architectures enable continuity deployment within existing IT rooms and clinical technology environments without requiring electrical-room reconstruction, supporting phased infrastructure modernization aligned with evolving healthcare system deployment models.

Rack-Integrated Modular Three-Phase Architecture

Engineered as a rack-first UPS platform, the M90C-2S delivers centralized continuity within a compact 6U chassis.

This deployment model supports:

  • micro-data-center infrastructure
  • secure IT room environments
  • clinical technology power protection
  • edge compute aggregation
  • industrial control clusters

Unlike floor-standing UPS systems, rack-integrated modular architectures enable centralized continuity within existing rack infrastructure.

Architectural Differentiators

Unity Power Factor Capacity Utilization

The M90C-2S delivers unity output power factor (1.0 PF), enabling full use of installed electrical capacity and reducing oversizing requirements common in legacy three-phase UPS systems.

Integrated Maintenance Continuity

An integral maintenance bypass enables service intervention without disrupting protected loads, eliminating the need for external bypass panels and improving lifecycle serviceability.

This feature is particularly valued in federal and healthcare infrastructure deployments.

Modular Runtime Scalability

The dual-slot architecture supports scalable runtime configuration while maintaining a consistent rack footprint.

System configuration requires:

  • one power module
  • one battery module

This enables phased runtime expansion without chassis replacement.

Flexible Power Connection Architecture

The M90C-2S supports rapid deployment through configurable connection options:

  • optional input line cord: L21-20P (5 kW) or L21-30P (8 kW)
  • optional receptacle panels: L21-20R or L21-30R
  • hardwire input supported

These options simplify installation across standardized 208 / 120 V infrastructure environments.

Compact Modular vs Facility-Scale Modular UPS

Rack-integrated modular UPS platforms such as M90C are typically selected when:

  • continuity must be deployed within rack environments
  • electrical room expansion is constrained
  • localized centralized protection is required
  • federal procurement compliance is necessary
  • healthcare modernization initiatives such as VA EHR modernization require phased infrastructure deployment

Facility-scale modular UPS platforms such as M90U are selected when:

  • infrastructure continuity capacity exceeds rack deployment thresholds
  • centralized electrical room deployment is preferred
  • enterprise-scale load growth is anticipated

Modular Portfolio Positioning

The M90C platform represents the compact rack-integrated three-phase modular tier within the Xtreme Power modular ecosystem.

M90C Capacity Planning Ladder

M90C-2S — 5–8 kW
Optimized for secure rack deployments and localized continuity requirements.

M90C-6S — 5–24 kW
Supports higher-density infrastructure aggregation and extended runtime scalability.

Infrastructure planners typically transition to larger modular chassis when aggregated load density exceeds compact deployment thresholds.

Lifecycle Modernization Benefits

Compact modular rack UPS architectures support modernization initiatives such as VA EHR modernization programs by enabling:

  • phased subsystem upgrades
  • reduced replacement disruption
  • standardized modular service workflows
  • predictable lifecycle cost management
