Vertiv Liebert EXS V-Model UPS 20kVA/20kW 208/120VAC(220/127VAC) 3-Phase 4 Wire

The Vertiv Liebert EXS V-Model UPS (EXSV-20KXRTN) is a compact, monolithic online UPS engineered to protect critical IT equipment with true online, double-conversion power conditioning. This technology continuously stabilizes output voltage, delivering a clean, stable power signal free from mains disturbances, voltage sags, interruptions, and transient spikes. Designed for servers, networking gear, storage arrays, and telecom equipment, the EXS V-Model keeps equipment online during utility disturbances and ensures consistent performance for your most demanding workloads. Its 20 kVA / 20 kW capacity, three‑phase 4‑wire input and output, and space-efficient footprint make it ideal for mid‑sized data rooms, server closets, and edge deployments where reliability is paramount. The UPS is built to withstand demanding environments, providing robust protection, predictable runtimes, and a straightforward path to scalable power protection as your infrastructure grows.

• True online, double‑conversion power conditioning: The EXS V-Model delivers continuous, clean output by separating the load from fluctuating input power. This eliminates line noise and voltage sags, preventing performance degradation or unexpected shutdowns of sensitive IT equipment. With precise voltage regulation and high input power factor, it ensures your critical devices receive consistent power under a wide range of utility conditions.
• High‑capacity 20 kVA / 20 kW, 208/120 VAC (220/127 VAC nominal), 3‑Phase 4‑Wire: Designed for data rooms and edge deployments, this UPS supports multi‑server environments and other demanding IT loads. The three‑phase configuration helps balance loads, reduces wiring complexity, and improves efficiency in larger IT closets compared with single‑phase options, while still delivering nimble, space‑saving performance in a compact tower footprint.
• Top Fan with SNMP for remote monitoring: Integrated monitoring capabilities enable proactive management from anywhere on the network. The top‑mounted fan module supports SNMP, enabling you to track health, runtime, battery status, and alerts, and to respond quickly to potential issues before they impact uptime. This feature helps streamline maintenance and contributes to more reliable operations in busy data environments.
• Runtime of 13 minutes at rated load: The EXSV‑20KXRTN provides a meaningful autonomous runtime to gracefully shut down or transition workloads during short outages, giving your IT team time to respond. While this runtime is specified for the rated load, the system is designed to work with Vertiv battery management options to suit longer outage scenarios, maintaining protection while you bring systems back online or switch to alternative power sources.
• Compact monolithic tower design for space‑efficient deployments: The streamlined, rugged enclosure is optimized for tight spaces in data rooms and edge locations. Its single‑unit, monolithic form factor simplifies installation, reduces cable clutter, and enhances serviceability, while delivering enterprise‑grade protection in a footprint suited to smaller footprints where floor space is at a premium.

how to install Vertiv Liebert EXS V-Model UPS

• Step 1: Select a location with sturdy flooring, adequate ventilation, and clear access for service. Ensure the space allows for required airflow around the unit and meets clearance recommendations for serviceability and heat dissipation.
• Step 2: Prepare the electrical connections. Use a proper 3‑phase 4‑wire input feed rated for the 20 kVA load. Follow local electrical codes for grounding and bonding. Plan routing for the UPS output to your critical loads (servers, storage, networking equipment) with appropriate wire gauge.
• Step 3: Position and connect the UPS. Place the EXSV‑20KXRTN in its intended location, align levelers if applicable, and connect the input power to the building utility. Verify all connections are secure and that the site can support service access for maintenance and battery replacement if needed.
• Step 4: Configure management and monitoring. Install the SNMP module as indicated and connect the management interface to your network. Configure IP address, SNMP community strings, and alert thresholds to integrate with your existing monitoring system or Vertiv Voyager/Liebert management tools.
• Step 5: Connect critical loads to the UPS output. Route servers, storage, and network devices to the UPS output receptacles or distribution as designed for your environment. Power up the system and perform a basic self‑test to verify healthy operation and battery status.
• Step 6: Verify run‑time and alarms. Initiate a controlled test to confirm the 13‑minute runtime at nominal load and ensure all alarm indicators, LEDs, and SNMP alerts function correctly. Schedule regular battery health checks and maintenance as part of your IT resiliency plan.
