Liebert NX Features The Liebert NX family of UPS systems offers a variety of operating features to meet a wide range of requirements:

Capacity Growth

νParallel for capacity — Up to 3 UPS modules may be used in a parallel configuration to provided added capacity as needs grow.

νParallel for redundancy — Up to 4 UPS modules may be used in a parallel configuration to provide redundancy for added reliability. Contact factory for switchgear options when paralleling more than 4 UPS modules.

νParallel unlike capacities — The Softscale technology of the Liebert NX allows you to change your growth increment without having to obsolete your existing UPS. For example, a Softscale UPS rated 80kVA can be paralleled with another Softscale UPS rated 120kVA for a combined output capacity of 200kVA.

νOptional paralleling cabinets — These cabinets include various switchgear configurations to parallel NX modules rated 20kVA or 30 kVA, or Softscale models rated 40kVA – 200kVA, for additional capacity and redundancy.

νSoftscale™ technology — The Liebert NX UPS Softscale capability provides fast software scalability. Purchase the capacity you need today, then when your power needs grow you simply purchase a software key and an Emerson Customer Engineer will visit your site to increase

the UPS capacity. Softscale models are available in the range of 40kVA to 80kVA; 80kVA to 120kVA, and 160 & 200 kVA.

Advanced Electronics

νDigital signal processor controls — The advanced topology of the Liebert NX features a digital signal processor (DSP) controlled IGBT

rectifier and IGBT inverter. Digital controls provide the fastest possible power management to enhance reliability, accuracy and efficiency while reducing component count.

Performance

νEco-Mode high efficiency configuration —

Operating mode that switches the UPS to static bypass during normal operation. When power problems are detected the UPS automatically switches back to double conversion mode.

νHigh overload protection — The system’s static switch overload rating makes it capable of clearing a 20 A branch circuit breaker. Handles 125% for 10 minutes, 150% for one minute and a 1000% overload for 10 milliseconds.

νBuilt-in automatic bypass — Transfers the load to bypass in the unlikely event that a fault occurs in the UPS.

νOptional maintenance bypass distribution cabinet — Provides complete

wrap-around maintenance bypass allowing UPS to be powered down or taken out of service without disconnecting power to the load.

νOptional internal batteries — Batteries can be housed within the UPS itself in Liebert NX 10, 15, 20 and 30 kVA sizes.

νOptional external battery cabinets — Provide added back-up capacity for extended runtimes.

νTriple-mode battery charger for fast battery recharge — Three charging modes ensure maximum battery availability:

•Constant current charging provides maximum rated current to the battery until the voltage rises to a pre-determined limit.

•Constant voltage charging allows the batteries to recover the final percentage of recharge capacity. A boost voltage is provided for a short term to reduce the battery recharge interval.

•Float charging maintains the battery at the recommend voltage.

Physical Characteristics

νIn-The-Row form factor — Liebert NX 40-200 kVA models are housed in IT rack style cabinets for easy integration within equipment rows.

νFront access service — Allows easy servicing of critical internal components.

νFront access installation — No need for side access when installing UPS.

νCompact footprint — Requires less floor space, leaving you with more room for other equipment.

Communications

νLiebert IntelliSlot® communications compatibility — Power communications available through Liebert IntelliSlot Web Card LB and Liebert MultiLink™ shutdown software.

νMulti-language LCD display — Large and user-friendly LCD display provides operating information in twelve languages.

νLiebert NX Softscale Service with Ntegrated Monitoring — Advanced monitoring and network security capabilities from the service business of Emerson Network Power provide an integrated approach to alarm management, predictive maintenance and emergency service response. Utilizes remote monitoring capabilities to provide periodic equipment condition reports, alarm retrieval and warehousing, escalation management, and 7 x 24 emergency

service response.

νUPS Service with Ntegrated Monitoring —

Advanced monitoring and network security capabilities from the service business of Emerson Network Power provide an integrated approach to alarm management, predictive maintenance and emergency service response.

νTrue on-line double conversion — Output power is regenerated inside the UPS, providing protection from the full range of power irregularities.

νOptimized Efficiency using Soft-switching technology — This design technique improves system efficiency and

maintains high efficiency performance from 40% to 100% utilization.

νIGBT-based input power factor corrected rectifier — Enables the Liebert NX to achieve its impressive THD and PF performance.

νDual bus synchronization — Provides the capability to synchronize the outputs of two independent UPS when they are configured as a redundant system feeding independent distribution paths.

Warranty/Service

νOne year warranty — Standard warranty provides full coverage for one year.

νOptional start-up of UPS — factory trained service personnel ensure proper start-up of the UPS. This option extends the one year warranty to include labor and travel.
