Riello M2U 40kW

The M2U 40kW is built for the “always-on” requirements of modern IT. By using Unity Power Factor, it ensures that the 40kVA rating delivers a full 40kW of active power. The system is designed around a “no single point of failure” philosophy. Everything from the power modules to the bypass and control logic is designed to be redundant and hot-swappable, allowing for maintenance or upgrades without ever switching your critical load to unprotected utility power.

Product Description

Key Features & Benefits

  • High-Efficiency Design: Achieves up to 97% efficiency in online double-conversion mode, significantly reducing the “heat tax” in your server room and lowering utility bills.

  • Seamless Scalability: Housed in a frame that often supports up to 68kW or 100kW, you can scale from 40kW to a higher capacity simply by sliding in additional 20kW modules.

  • Hot-Swappable Modularity: Every major component can be replaced while the UPS is running, reducing Mean Time to Repair (MTTR) and eliminating the need for scheduled downtime.

  • Superior Battery Management: Compatible with VRLA and Lithium-ion energy storage, featuring sophisticated charging algorithms that protect battery health and extend service life.

  • Small Footprint: Designed to fit into standard data center rows, the “Combo Cabinet” version includes both the UPS modules and internal batteries in a single slim enclosure.

  • 10-inch Color Touchscreen: Provides a sophisticated dashboard for monitoring power flow, module status, and historical event logs at a glance.
