Xtreme – M90S-4S – 6000 – 6 KVA – Online UPS

Xtreme Power M90S-4S Modular UPS — 6 kW Tower or Rack Mount, Online Double-Conversion

The Xtreme Power M90S-4S is a 4-slot modular UPS enclosure designed for maximum flexibility, efficiency, and uptime in single-phase environments. Rated for 6 kW or 12 kW depending on the number of installed power modules, the M90S-4S delivers true online double-conversion protection, ensuring your mission-critical equipment always sees clean, regulated AC power — regardless of utility disturbances.

By combining universal slots (each slot can accept either a power module or a battery module), a front-access maintenance bypass, and per-module LCD displays, the M90S-4S gives you the performance, visibility, and scalability needed for modern IT racks, AV systems, and industrial controls. It can be deployed as a compact tower or integrated as a rack-mount UPS using the appropriate rails, making it versatile platform for new builds and retrofit installations alike.

Key Features & Benefits

• Universal slot design — Each of the four slots can accept either a power module or a battery module, allowing you to tune capacity and runtime per site.
• Flexible ratings— Configure the UPS for 6 kW or 12 kW output depending on the number and size of installed power modules.
• Online double-conversion— Provides continuous, clean, and regulated AC output for servers, storage, AV gear, and control systems.
