M90LU Modular UPS for Extended Runtime Applications

15kW–60kW | 208/120VAC Three-Phase | Scalable External Battery UPS

The Xtreme Power M90LU Modular UPS delivers long-duration backup power for facilities requiring extended battery autonomy. Designed for use with M90-BC, M90-BOS, or approved third-party battery cabinets, the M90LU provides exceptional runtime scalability by operating without internal batteries—ideal for mission-critical environments that depend on long hold-up times.

With unity power factor (1.0 PF) output, hot-swappable modules, N+1 redundancy, and up to 94% online efficiency (98% ECO mode), the M90LU ensures continuous uptime while reducing energy and cooling costs. Its compact 30-inch cabinet height reduces vertical clearance requirements and helps the UPS fit into space-restricted electrical rooms, IDFs/MDFs, and modular data center environments. TAA compliance supports U.S. federal and public-sector installations.
