Emerson Network Power Adds Capacity & Integrates Battery Monitoring Solution To Liebert NXL UPS Platform
Emerson Network Power announced that it has raised the capacity of its Liebert NXL™ UPS (uninterruptible power supply) system to 750kVA and enabled its Albér BDSi monitoring solution to be integrated into the matching Liebert NXL battery cabinet, if chosen as an option.
The Liebert NXL, which is designed for medium and large data centers, is available in capacities starting at 250 kVA. As facilities seek increased protection and/or system flexibility, the new 750 kVA model is available in single module and multi module systems (N+1 or 1+N) to achieve redundancy and maximum reliability.
The Liebert NXL is said to be one of the first UPS systems to be listed to the new UL 1778 fourth edition requirements. It is engineered with a design that allows it to operate at more than 100% load under certain simultaneous conditions that would require other systems to de-rate their output. Conditions such as high ambient temperature, high altitude, and low- and high-line conditions have been mitigated to ensure full rating at 100 percent operating loads.
The Liebert NXL platform features a comprehensive line of matching ancillary products that enhance system flexibility and availability. These include: maintenance bypass cabinet allows UPS maintenance without load power down; module battery disconnect houses an external battery circuit breaker that isolates the UPS module from external battery solutions; system control cabinet allows control of parallel systems with up to six UPS units and contains the system static bypass switch; and matching battery cabinet features a breaker for safe battery service without shutdown and can be equipped with the Albér BDSi battery monitoring solution.
All cabinets allow easy configuration and line-up installation with internal cabling, providing savings on installation cost and footprint.
The optional Albér BDSi battery monitoring solution enables users to extend and optimize useful battery life, reduce maintenance costs, and increase safety by proactively managing system batteries. It monitors all of the 12V sealed batteries in the Liebert NXL UPS battery cabinet, and can be configured to support up to six battery cabinets. The monitoring system reports all critical battery parameters, including internal resistance, total voltage, cell voltage, temperature, and discharge events. This option is factory installed and tested within the Liebert NXL battery cabinet to ensure proper operation and reduce field start-up requirements. Retro-fit solutions are available for Liebert NXL UPS battery cabinet units already installed.
Additionally, facility and data center managers can enlist in a program enabling Emerson Network Power’s Liebert services team to remotely monitor and report on battery status, and make recommendations for proactive battery replacement. The Battery Service with Ntegrated Monitoring™ program includes battery and Alber BDSi preventive maintenance, firmware upgrades, an extended warranty and equipment startup.
