Xtreme Power M90S-6S Modular UPS — 18 kW, Tower or Rack Mount, Online Double-Conversion

The Xtreme Power M90S-6S is a 6-slot modular UPS enclosure designed to deliver scalable, high-availability power for demanding single-phase applications. With a capacity range of 12 kW, 18 kW, or 24 kW, the M90S-6S provides true online double-conversion protection, ensuring your AV, broadcast, and IT equipment always sees clean, regulated AC power – even under poor utility conditions.

Each of the six universal slots can accept either a power module or a battery module, giving you maximum flexibility to balance capacity and runtime as your environment evolves. Combined with hot-swappable modules, an integrated front maintenance bypass, and both system-level and per-module LCD displays, the M90S-6S offers the performance, visibility, and serviceability required for mission-critical racks in a tower or rack-mount deployment.
