Rack-Integrated 400V Modular Architecture

M90Ci-2S enables deployment of three-phase 400 V UPS protection directly within the rack environment. By integrating power and battery modules into a compact chassis, it supports localized three-phase protection without requiring centralized UPS systems. This reduces infrastructure footprint, simplifies deployment, and improves service accessibility. This approach aligns with distributed power architectures used in modern data centers and industrial systems.

Modular UPS vs Traditional Three-Phase UPS

Traditional three-phase UPS systems are centralized, fixed in capacity, and require larger electrical room infrastructure. M90Ci-2S delivers three-phase power in a compact modular architecture, enabling localized deployment within the rack. This simplifies installation, reduces infrastructure requirements, and improves serviceability.

Electrical Integration and Deployment

M90Ci-2S is designed for permanent installation with hardwired input and output connections. Integrated maintenance bypass enables safe load transfer during service, while modular components allow simplified replacement and reduced downtime.

Performance Characteristics

Online double-conversion topology delivers continuous conditioned power isolated from upstream disturbances. Unity power factor ensures full real power delivery, while high operating efficiency reduces energy losses. The system is designed to support modern 400 V infrastructure across a wide range of environments.

Why M90Ci-2S

M90Ci-2S is selected for applications where:

  • Three-phase power is required within the rack
  • Infrastructure is distributed across multiple locations
  • Compact deployment is required
  • Modular serviceability improves uptime

Replace Eaton and Vertiv UPS Systems

M90Ci-2S is commonly deployed as a replacement for compact three-phase UPS systems and modular platforms from Eaton and Vertiv. It enables modernization by introducing rack-integrated deployment, modular serviceability, and improved efficiency within a compact system. It is also a strong replacement for legacy Eaton BladeUPS systems, supporting migration to modern 400 V architectures.
