About the Vertiv Liebert MPX 25kVA 3-Phase Rack-Mount UPS

The Vertiv Liebert MPX 25kVA is a compact, three-phase rack-mount uninterruptible power supply engineered for space-constrained enterprise environments. This unit bridges the capacity gap between single-phase UPS systems and larger floor-standing installations, delivering 25kVA / 20kW of continuous power in a standard rack form factor. The MPX architecture supports modular scalability and advanced power management, making it suitable for facilities requiring high density and reliability without extensive footprint requirements.

Designed for infrastructure environments with three-phase power distribution, the MPX 25kVA operates on 208V, 240V, 380V, 400V, or 415V three-phase input configurations. The system features a bypass switch for seamless utility transfer and supports both double-conversion and eco-mode operation modes to optimize efficiency during normal grid conditions. Battery runtime extends based on load level and external battery cabinet configuration.

Ideal for

  • Telecom central offices and edge computing POPs requiring compact, high-capacity power protection
  • Data center colocation facilities with limited rack space and three-phase power infrastructure
  • Enterprise network closets and equipment rooms consolidating critical IT loads
  • Regional processing hubs and 5G network equipment deployments
  • Financial services branch offices with distributed computing requirements
  • Healthcare facilities requiring reliable power for imaging and diagnostic equipment
