The M90U is XPC's facility modular platform (15 to 140 kW at 208/120V with modular N+1 redundancy) built from hot-swappable 15/20 kW power and battery modules behind a full wrap-around maintenance bypass. XPC cites a footprint that saves up to 40% of floorspace versus comparable systems. Four variants cover the range: M90U (15 to 60 kW, internal battery), M90LU (external battery, extended runtime), M90U-80 (to 80 kW in one cabinet) and M90U-140 (to 140 kW with the M90-BC enclosure).
If you're running a legacy fixed-capacity centralized UPS that's aging or near end of life (say an APC Symmetra, an Eaton BladeUPS or a Vertiv Liebert EXM) the M90U is built to take its place: instead of swapping one monolithic box for another, you move to a platform you scale a module at a time, with N+1 redundancy and per-module serviceability. Tell us the unit you're replacing and your load, and we'll size, supply and install the M90U to match.

Battery strings and cabinets depend on the configuration and runtime. Batteries for Xtreme Power UPS cabinets are matched by string voltage and block size.
We service the XPC M90U across Canada: preventive maintenance, battery replacement and emergency repair, including units the manufacturer no longer supports. We are a Canadian UPS service and supply provider, working on three-phase systems since 2012.
Battery strings, capacitors and fans are checked as part of preventive maintenance for Xtreme Power UPS systems.
We engineer the solution: load and growth analysis, redundancy (N, N+1, 2N), runtime and battery sizing, paralleling and switchgear, and custom configurations where the standard catalogue doesn't fit. Because we supply every major brand, the M90U is one option we weigh on its merits, not the only answer.
