Xtreme – M90LU – 40000 – 40 kVA – Three Phase Online UPS

Xtreme Power M90LU Modular UPS — 40 kVA, 208/120V Three-Phase, External Battery Runtime

The Xtreme Power M90LU is a modular three-phase UPS engineered specifically for
long-duration backup using external battery cabinets. Operating at 208/120VAC three-phase with
unity power factor (1.0 PF) output, the M90LU is designed to pair with M90-BC, M90-BOS, or
approved third-party battery cabinets to deliver highly scalable runtime—ideal for mission-critical environments
that require extended hold-up times and modular capacity growth.

With hot-swappable power modules, N+1 redundant configurations, and up to 94 % online efficiency
(98 % ECO mode), the M90LU ensures continuous uptime while helping reduce energy and cooling costs.
Its compact 30-inch cabinet height minimizes vertical clearance requirements, making it a perfect fit for
space-restricted electrical rooms, IDF/MDF closets, and modular data center deployments. TAA compliance allows
the M90LU to be deployed in U.S. federal, defense, and public-sector installations without procurement concerns.

Key Features & Benefits
