Vertiv Liebert EXS V-Model UPS 20kVA/20kW 208/120VAC (220/127VAC) 3-Phase 4 Wire – Top Fan w/ SNMP, 13 min Runtime

The Vertiv Liebert EXS V-Model UPS (EXSV-20KXRTN) is a compact, monolithic online uninterruptible power system designed to protect critical IT infrastructure with unwavering reliability. Built around true online, double-conversion technology, this 20 kVA / 20 kW UPS delivers a pristine output voltage that stays steady even as input power fluctuates, ensuring your servers, storage systems, and networking gear run without interruption or voltage distortion. The 3-phase, 4-wire configuration supports modern data centers and edge deployments that require robust power distribution across multiple loads, while the device’s compact tower form factor makes it suitable for tight data rooms, equipment closets, or distributed IT cabinets. A top-front cooling fan keeps hot components within optimal temperatures, helping extend component life and maintain consistent performance in warmer environments. Integrated SNMP support provides seamless remote monitoring and alerting, letting IT teams stay ahead of potential issues and plan proactive maintenance. With a measured runtime of up to 13 minutes at full load, the EXSV-20KXRTN offers a prudent window for orderly shutdowns, load shedding, or transition to an alternate power source during outages. The EXS V-Model is designed not only for peak protection but also for straightforward installation, efficient serviceability, and thoughtful lifecycle management, aligning power reliability with aggressive IT service-level targets and total cost of ownership considerations.

• Advanced online power conditioning: True online, double-conversion technology continuously filters input power and regenerates a clean, regulated output. This protects sensitive servers, virtualization hosts, storage arrays, and network gear from voltage sags, spikes, harmonic distortion, and transient disturbances, delivering a stable sine-wave output that supports precise timing, reliable boot sequences, and data integrity during power events.
• 3-Phase, 4-Wire compatibility for scalable IT: The 208/120 VAC (with 220/127 VAC support) configuration is ideal for data centers and enterprise networks that require multi-load distribution across three hot phases and a neutral. This arrangement reduces neutral currents, improves fault tolerance, and enables efficient load balancing across multiprocessor servers, high-density blades, and network equipment while maintaining tight voltage regulation for each connected device.
• Compact tower design with effective cooling and remote management: The vertical footprint fits compact rooms and space-constrained environments, yet it maintains robust airflow with a top-front cooling fan. Coupled with SNMP networking, administrators can monitor voltage, load, battery health, and runtime from existing management platforms, receive proactive alerts, and implement power policies that minimize downtime and optimize uptime guarantees for mission-critical workloads.
• Competitive runtime for outage scenarios: With an approximate 13-minute runtime at full load on the EXSV-20KXRTN, you gain the essential margin to perform orderly shutdowns, migrate workloads, or bridge short outages. This runtime is valuable in environments where automated shutdown scripts, virtualization platform integration, or battery-backed storage must preserve data integrity while maintenance activities are underway.
• Ease of integration and serviceability: The EXS V-Model is designed for straightforward installation and long-term maintenance. Its modular architecture and clear diagnostics help facilities teams and IT staff minimize downtime, simplify battery replacements when necessary, and manage lifecycle costs with predictable service intervals and scalable protection as your IT footprint expands.

How to install Vertiv Liebert EXS V-Model UPS

• Plan the installation area: choose a clean, climate-controlled room with adequate airflow, clearance for air intake and exhaust, and a solid, level surface capable of supporting the unit’s weight and shock loads during transit or maintenance.
• Inspect and prepare the unit: verify model (EXSV-20KXRTN) and serial numbers, inspect for transit damage, and remove the packaging only after confirming there are no transport-related issues.
• Position and secure: place the UPS in a dedicated space on the floor or within a compatible cabinet, ensuring stable mounting and sufficient space around the unit for ventilation and service access.
• Electrical connections: connect the UPS input to a properly rated 3-phase, 4-wire power source with appropriate protective devices and grounding per local electrical codes. Then connect the UPS output to your IT distribution panel, wiring per manufacturer guidelines and ensuring correct phase balance and neutral bonding.
• Network and monitoring setup: install the SNMP management option (if not already integrated), assign an IP address, configure community strings or authentication as required by your network management system, and enable alerting for voltage, load, battery health, and faults.
• Initial startup and testing: perform a factory self-test or an auto-test routine, verify battery status, and conduct a controlled load transfer test to confirm automatic startup during outages. Validate that connected equipment boots successfully and that monitoring dashboards accurately reflect runtime, load, and power quality.
• Documentation and maintenance planning: record serial numbers, warranty details, and service intervals. Establish a preventive maintenance schedule that includes battery health checks, firmware updates when available, and inspection of ventilation components to sustain reliability over the device lifespan.
