XPC M90: key facts

Sources, checked October 3, 2026: Xtreme Power Conversion, M90.

Is the XPC M90 discontinued? What replaces it?

Yes. Xtreme Power Conversion states that the M90 has been replaced by the M90U, the current model in this platform. See the XPC M90U page.

Units already installed keep working after the manufacturer's cut-off; what changes is parts and factory support. We maintain discontinued units and plan the replacement when it makes sense. How to plan the replacement of a discontinued three-phase UPS.
