M90C-2S & M90Ci-2S UPS Comparisons

Compact Modular Three-Phase UPS Comparisons for 208 V and 400 V Applications

The Xtreme Power M90C-2S (208/120 V) and M90Ci-2S (400/230 V) are compact modular online double-conversion three-phase UPS platforms designed for edge data centers, enterprise IT, industrial control, and distributed infrastructure environments requiring high efficiency, front-access serviceability, and integrated maintenance bypass.

Both platforms use a dual-slot modular architecture with hot-swappable power and battery modules, delivering unity power factor output and scalable runtime in a compact 6U rack form factor. The M90C-2S serves North American 208 V deployments, while the M90Ci-2S supports global 400 V infrastructures.

This hub provides a unified view of how the M90C-2S and M90Ci-2S compare to Eaton and Vertiv compact three-phase UPS alternatives across serviceability, lifecycle status, topology, and footprint.
