M90Ci-6S Modular UPS – Compact Three-Phase Rack/Tower Power System

10kW – 60kW | 400/230 VAC Modular Three-Phase | Scalable Unity Power Factor UPS

The Xtreme Power M90Ci-6S delivers modular, high-efficiency three-phase power protection for data centers, industrial automation, and edge-computing environments operating at 400/230 V.

The M90Ci-ENC6 cabinet includes six total slots — five universal for either power or battery modules, plus one dedicated power slot. Each 10 kW module is hot-swappable, supporting configurations from 10 kW to 60 kW or N+1 redundancy. Internal batteries power systems up to 30 kW, while the M90Ci-BC7 battery cabinet holds up to seven battery modules for extended runtime.

Certified to CE and IEC 62040, the M90Ci-6S offers unity power factor and up to 94 % online efficiency for globally compliant, energy-optimized performance.
