The EXS V-Model is optimized for modern IT loads where uptime matters. Its compact, tower-form factor delivers high capacity in a space-saving design, while advanced cooling, SNMP-based remote monitoring, and a straightforward maintenance path minimize downtime and administrative overhead. Whether you’re refreshing an aging power protection system or expanding your IT footprint, this 40kVA/40kW unit provides dependable standby power, fast transfer times, and a predictable, clean sinewave output that keeps equipment performing at peak levels even during brownouts, sags, and brief outages.

• True online, double-conversion power conditioning: Delivers a pristine output waveform with low total harmonic distortion (THD) and seamless ride-through, protecting sensitive IT gear from input voltage sags, spikes, and interruptions. This ensures consistent performance for critical workloads and reduces anomaly rates across your infrastructure.
• High-capacity 40 kVA / 40 kW UPS for IT resilience: Delivers substantial reserve margin to support mid-size data centers, virtualization hosts, and clustered server environments. The EXS V-Model is purpose-built to handle demanding workloads while maintaining compact physical footprint.
• Three-phase, four-wire input with flexible output configurations: Operating at 208/120 VAC input (220/127 VAC nominal), this unit supports a balanced, scalable deployment suitable for modern data hall power distribution. Its topology is optimized for high efficiency and stable voltage regulation across a wide load range.
• Top Fan cooling with SNMP monitoring: A purpose-driven cooling system keeps the UPS operating within its thermal envelope, while SNMP compatibility enables remote monitoring, alerting, and integration with existing management platforms. This simplifies maintenance, asset tracking, and proactive fault handling.
• Runtime and maintenance-friendly design: The EXSV-40KTN offers a practical run time of approximately 6 minutes at full load, providing a buffer for orderly shutdowns or transitions to bypass during maintenance or power disturbances. Its monolithic, tower-style form factor supports straightforward installation and serviceability, reducing total cost of ownership.

how to install EXSV-40KTN

Installing the Vertiv Liebert EXS V-Model UPS should be performed by qualified electrical personnel in accordance with local codes and manufacturer guidelines. Begin by selecting a stable, well-ventilated location with adequate clearance for service access, cable routing, and future maintenance. The tower form factor is designed to stand securely on a level floor or be mounted in an appropriate equipment rack if needed, ensuring that the weight and dimensions align with the space and floor-loading requirements.

Prepare the electrical connections by evaluating your facility’s power distribution plan. Route input cabling from the main distribution panels to the UPS input, ensuring that you observe proper phase balance and protective devices. Connect the output to the IT loads via the recommended distribution path, which may include PDU(s) or switchgear configured for three-phase, four-wire operation. Ensure all connections are tight, properly protected, and compliant with electrical codes. After connecting power, attach the SNMP management card or interface to enable remote monitoring and alerting. This step unlocks early fault detection, precise runtime information, and proactive maintenance capabilities.

Commissioning should include a thorough functional test: verify battery status, perform an online transfer test to confirm seamless handover between mains and UPS output, and check the SNMP connection for correct device identification, status flags, and alert thresholds. Validate that the run-time capability aligns with expectations by simulating a short outage and observing the UPS response, transfer times, and load integrity. Finally, establish maintenance schedules, battery service intervals, and a recovery plan to minimize downtime during real outages. Regular firmware updates and security patches, when provided by Vertiv, should be applied to maintain optimal performance and protection against evolving threats.

During ongoing operation, monitor the system through the SNMP interface or compatible management software. Track metrics such as input/output voltage stability, load percentage, battery health, and thermal status. Set up alerting for critical conditions like over-temperature, battery deterioration, or abnormal waveform properties so that your operations team can respond promptly. Routine inspections, dust control, and fan maintenance will help sustain peak efficiency and prolong the service life of the EXSV-40KTN.
