M90S Scalable Infrastructure Power Platform
A modern modular single-phase UPS architecture — engineered for scalable infrastructure continuity across distributed and centralized environments running on split-phase power. Phased capacity growth and lifecycle serviceability without disruptive replacement or a forced transition to three-phase distribution.
Why modular single-phase architecture exists
Technology density keeps rising in environments historically served by distributed rack-level UPS — telecom aggregation nodes, distributed compute, broadcast facilities, clinical electrical support, and large residential technology deployments increasingly need structured continuity planning. Legacy deployment models introduce structural limitations:
- Fixed-capacity systems require full replacement for growth
- Distributed UPS proliferation increases operational complexity
- Electrical-room constraints limit scalability
- Redundancy coordination becomes difficult
- Modernization initiatives require phased capital investment
Modular single-phase architecture lets continuity infrastructure scale predictably with operational requirements.
Split-phase infrastructure constraints
Many facilities run on 208/120V or 240/120V service where moving to three-phase distribution is impractical because of:
- Building electrical design limitations
- Service-upgrade cost and disruption
- Constrained electrical-room environments
- Distributed facility layouts
- Phased infrastructure modernization planning
The point: modular single-phase UPS platforms enable centralized continuity strategies without fundamental electrical-system reconstruction.
Centralized vs. distributed modular deployment
The M90S supports both centralized and distributed modular continuity strategies — and hybrids of the two.
Centralized deployment
- Aggregated protection across multiple critical loads
- Unified runtime and battery-lifecycle management
- Structured redundancy planning
- Simplified service workflows
- Improved electrical-room infrastructure density
Distributed modular deployment
- Localized continuity aggregation
- Phased infrastructure expansion
- Reduced initial deployment complexity
- Incremental modernization strategies
- Site-specific continuity design flexibility
Hybrid deployment models are common — particularly across distributed campus, telecom, and multi-building facility environments.
Standardized 6 kW modular blocks
The M90S is built on standardized 6 kW modular power blocks, forming a scalable continuity framework that supports:
- Predictable capacity expansion
- Subsystem-level lifecycle replacement
- Runtime-optimization flexibility
- Structured redundancy modeling
- Standardized service ecosystems
Universal modular slots. Planners dynamically allocate power and battery modules within a unified chassis. Operational integrity requires at least one active power module and at least one battery module.
What sets the M90S apart
Unity power factor utilization
- Unity output power factor (1.0 PF) — full utilization of installed electrical capacity
- Legacy modular platforms commonly run reduced PF (0.8–0.9), increasing oversizing risk
- Improved infrastructure-density planning
- Reduced electrical-system oversizing
- Higher usable capacity per installed kVA
Integrated maintenance continuity
- Integral maintenance-bypass framework — service without interrupting protected loads
- Safe maintenance-isolation workflows
- Reduced service-disruption exposure
- Elimination of external bypass-panel dependency
- Improved centralized-infrastructure reliability
Single-phase vs. three-phase
Choose modular single-phase when
- Facility electrical service remains split-phase
- Aggregated load density exceeds distributed-UPS practicality
- Phased infrastructure growth is required
- Modernization must avoid electrical reconstruction
Three-phase becomes appropriate when
- Infrastructure density exceeds practical single-phase aggregation limits
- Electrical-room design supports higher-capacity centralized continuity
- Enterprise-scale infrastructure expansion is anticipated

Modular lifecycle modernization
Centralized modular UPS architecture enables structured modernization by supporting:
- Phased subsystem renewal instead of full system replacement
- Reduced operational-disruption risk
- Standardized spare-parts frameworks
- Predictable long-term capital planning
- Continuity-aligned maintenance methodologies
This lifecycle model aligns continuity infrastructure with contemporary facility-engineering practice.
The M90S modular tiers
A standardized framework that scales with infrastructure demand while maintaining platform consistency:
Specifications by tier
Every M90S frame shares the same online double-conversion core, unity power factor, and 6 kW modular building block. The frames differ in slot count, capacity, display, and form factor:
| Specification | M90S-2S | M90S-4S | M90S-6S ★ | M90S-12S |
|---|---|---|---|---|
| Slots | 2 | 4 (2 universal + 2 battery) | 6 (4 universal + 2 battery) | 12 universal |
| Capacity | 6 kW | 6–12 kW | 6–24 kW | 6–48 kW |
| Capacities | 6 kW | 6 / 12 kW | 6 / 12 / 18 / 24 kW | 6–48 kW (6 kW steps) |
| Display | LCD power metering | 5.7″ graphic LCD | 5.7″ graphic LCD | 10″ color touch LCD |
| Per-module LCD | — | Yes | Yes | Yes |
| Redundancy | — | N+1 capable | N+1 capable | N+1 capable |
| Form factor | 19″ rack (6U) or tower | Floor-standing | Floor-standing | Floor-standing |
| Receptacle panels | Up to 1 | Up to 2 | Up to 4 | Terminal connections |
| Enclosure (W×D×H) | 17.3″×31.5″×10.5″ (rack) | 17.4″×33.7″×33″ | 17.4″×33.7″×45.5″ | 23.6″×36″×79.1″ |
M90S-12S: full 48 kW output requires 240/120V service; at 208/120V the maximum is 42 kW. N+1 redundancy is configured within installed slot capacity and is not implied at a frame’s fully-populated maximum.
