Liebert NXL (250-750kVA)

Liebert NXL uninterruptible power supply (UPS) provides reliable data center power protection and advanced technology for high power applications. This UPS adds dynamic performance to data center design, handling virtually any input condition while still providing computer-grade output to critical loads.

Liebert NXL UPS is available in single-module systems, with capacities of 250, 300 and 400 and 750kVA at 480V, 60Hz. Multi-Module 750kVA models are available in both 1+N (Distributed Static Switch) and N+1 (Centralized Static Switch) configurations. Add matching battery cabinets and a maintenance bypass cabinet for a complete power solution.

Liebert NXL battery cabinets are available with factory-integrated Alber BDSi battery monitoring. This factory installed and tested system continuously monitors and diagnoses battery parameters. The reporting function keeps data center personnel informed of battery health, and allows proactive battery replacement at the right time -- not prematurely or after a cell failure. Battery monitoring may also be managed by Liebert Services, ensuring proper, timely maintenance by local, trained Customer Engineers.
