80 kW Modular Online UPS Comparison for 208/120 V Three-Phase Applications
Modular 208/120 V three-phase UPS systems are widely deployed in data centers, telecom, and distributed IT environments requiring scalable capacity and high availability. The Xtreme Power M90U-80 and Eaton BladeUPS are modular UPS platforms designed for these applications.
BladeUPS systems (12–60 kW) are discontinued and limited to approximately 10 kW per module in continuous online operation. The M90U-80 delivers full online double-conversion output with larger power modules, longer runtime, and active lifecycle support scalable to 80 kW.
For facilities replacing BladeUPS or expanding modular 208 V infrastructure, the M90U-80 provides a modern, fully supported modular UPS platform.
