Frequently Asked Questions

• How can I get the most out of my investment?
  Liebert NXr, with its unity power factor (kVA=kW), offers more real power to support customer’s mission critical loads.
  
  With up to 96% online double conversion efficiency, Liebert NXr saves you operating cost compared to most traditional UPS in the market.
  
  
• How can I get optimum protection for my network with Liebert NXr?
  The double conversion technology of Liebert NXr allows it to have an above average industry standard of up to 96% efficiency, giving your network and data centre equipment full protection at the most efficient rate.
  
  
• How can I get the highest levels of Protection and Availability?
  Liebert NXr gives you built-in reliability with its stratified cooling technology, allowing cooling of critical components and redundant cooling fan option. Wider input voltage and frequency tolerances contribute to high power availability.
  
  Digital controls provide the fastest possible power management to enhance reliability, accuracy and efficiency while reducing component count. Dual bus compatibility and system redundancy further enhance the availability of a power.
  
  High overload protection handles 110% overload for 60 minutes, 125% for 10 minutes, and 150% for 1 minute.
  
  
• How can I save on my electricity bill and investment costs?
  The improved input power factor of the Liebert NXr can actually reduce your electricity usage. It delivers the highest possible input power factor - greater than 0.99 at rated linear and non-linear loads - for maximum efficiency.
  
  The unique ability of the Liebert NXr to adjust power walk-in from 5 seconds to 30 seconds, along with reduced input current distortion and power factor correction, also enables you to save money by reducing back-up generator sizing requirement.
  
  The unit’s compact footprint requires less floor space, leaving you with more room for other equipment.
  
  The Liebert NXr has built in Parallel and Load Bus Synchronization (LBS) boards. No extra hardware is needed, it may be easily connected just with control cables.
  
  
• How can I satisfy the requirements of the latest servers?
  Liebert NXr is capable of driving wide ranges of loads, from 0.5 lagging to 0.9 leading. This makes the UPS follow the latest IT industry trends, with more active power available for all kinds of loads.
  
  
• How can I also protect also my upstream-connected devices?
  The Liebert NXr provides the cleanest level of upstream power with the lowest level of input current THDi in the industry. This ensures that clean power flows upstream, avoiding damage to other loads connected to the upstream power distribution bus.
  
  
• How can I extend the system when I need more power?
  Liebert NXr features easy and simple scalability and redundancy. In fact, up to four Liebert NXr modules may be paralleled in a redundant configuration for added reliability and serviceability. The Liebert NXr is compatible with Liebert‘s unique LBS.
  
  
• How can I ensure the UPS will work under the most severe conditions?
  The wide input voltage window of 305V-477V and a frequency tolerance of 40Hz to 70Hz provide high quality power, even when input parameters are below standard. This helps minimize transfer to battery, reducing the charging and discharging cycles.
  
  Back-feed protection sensing ensures system integrity.
  
  Short-circuit-proof, DSP controlled inverter provides highest output power quality.
  
  
• How can I easily maintain my UPS?
  Liebert NXr includes a built-in maintenance bypass, with IP 20 UPS enclosure protection - even with the front doors open.
  
  Redundant configuration allows you to utilize one module while the other is being serviced.
  
  Dual bus compatibility enables you to transfer the load to an alternate power source for maintenance activities.
  
  
• How can I monitor and communicate with my UPS?
  To meet a variety of needs, the Liebert NXr offers communications through web or management systems through MODbus and SNMP communication protocol.
  
  
• How can I check the status of my UPS?
