Riello M2U 25kW

The M2U 25kW is part of Riello’s next-generation modular series, engineered to eliminate single points of failure while maximizing energy savings. With its Unity Power Factor (kW = kVA), this 25kW unit provides a full 25kW of active power to support modern IT loads without any derating. Its modular design allows for vertical scalability by simply add more modules to increase capacity or create an N+1 redundant system without taking the critical load offline.

Product Description

Key Features & Benefits

  • Silicon Carbide (SiC) Efficiency: The use of SiC components allows the M2U to reach up to 97% efficiency in true online double-conversion mode, drastically reducing heat dissipation and annual cooling costs.

  • Ultimate Availability: The system features a “Smart Modular Architecture” where every module (power, bypass, and control) is hot-swappable and independent, ensuring the load remains protected during maintenance or expansion.

  • High Power Density: The “Combo Cabinet” (CBC) houses both the power modules and internal battery shelves in a single, standard-width rack footprint, making it ideal for space-constrained Edge or server rooms.

  • Intuitive Control: Equipped with a high-definition 10-inch color touchscreen that provides real-time data, detailed event logs, and status information for every individual module in the cabinet.

  • Generator Friendly: With an input current distortion (THDi) of <3%, the M2U is perfectly compatible with standby generators, preventing electrical “noise” from affecting other sensitive equipment.

  • Sustainable Operation: Designed with the latest eco-friendly materials and high-efficiency logic to reduce carbon footprint and operational overhead.
