Vertiv Liebert EXM2 UPS 250kVA

The Vertiv Liebert EXM2 250kVA is a double-conversion online UPS system built on a modular, scalable architecture that ensures continuous, clean power delivery to mission-critical IT infrastructure. Operating at up to 97% efficiency in ECO mode and maintaining greater than 96% efficiency in double-conversion mode, the EXM2 dramatically reduces operational energy expenditure compared to legacy UPS platforms. Its advanced IGBT-based rectifier and inverter topology delivers a true online double-conversion design that completely isolates connected loads from utility power anomalies including sags, swells, harmonics, and outages, making it ideally suited for environments where power quality directly impacts system uptime and data integrity.

The Liebert EXM2 250kVA supports both traditional VRLA lead-acid batteries and next-generation lithium-ion battery modules, giving facilities teams the flexibility to select the chemistry that best aligns with their space, weight, and total lifecycle objectives. Lithium-ion compatibility translates to a significantly reduced battery footprint—often 50–70% smaller than equivalent VRLA installations—along with faster recharge times, longer service life, and reduced maintenance cycles. The unit's input power factor of 0.99 and low total harmonic distortion (THDi < 3%) at the input reduce the burden on upstream generators and utility feeds, simplifying electrical infrastructure planning for new builds and retrofits alike.

Designed with a small physical footprint and front-access serviceability, the EXM2 is optimized for high-density data center environments where floor space is at a premium. The integrated Liebert IntelliSlot communication bay supports a range of network management cards, enabling full integration with data center infrastructure management (DCIM) platforms, building management systems (BMS), and remote monitoring portals. Comprehensive protection features—including configurable bypass, intelligent battery management, and multi-level fault detection—combine with its high power density to position the EXM2 as a flagship solution for colocation providers, enterprise data centers, and critical facility operators deploying or expanding capacity in 2025 and beyond.

Ideal for

• Protecting high-density server and storage clusters in enterprise and colocation data centers requiring continuous double-conversion power conditioning against grid instability
• Supporting edge data center deployments where floor space constraints demand a compact high-kVA UPS capable of lithium-ion battery integration to minimize battery room footprint
• Providing clean, conditioned power to hyperconverged infrastructure (HCI) nodes and all-flash storage arrays sensitive to voltage fluctuations and micro-interruptions
• Serving as the primary UPS tier for medical imaging and clinical data systems in healthcare facilities where power quality directly impacts life-critical diagnostic equipment
• Powering telecommunications central office equipment and 5G network edge nodes where utility power quality is inconsistent and generator transfer times must be bridged seamlessly
• Enabling staged capacity expansion in financial services data centers by leveraging modular scalability to add runtime or power capacity as compute loads grow
