FEATURES

BENEFITS

Total cost of
ownership (TCO)

 

 

• High Efficiency

• Greatly reduces operational 
  expenses

• Unprecedented integrated
  autonomy

• Virtually eliminates the need for an
  external battery cabinet and the
  costs associated with its installation

• 0.9 output power factor

• 11% more active power compared
  to a 0.8 PF UPS

• Unity input PF & low THDi <3%

• Minimizes installation costs by
  enabling the use of smaller
  generators, cabling and circuit
  breakers.

• Integrated circuit breakers

• Simplifies installation and reduces
  the need for external devices

• Wide voltage and frequency range

• Wide input parameter range
  ensure UPS always run on utility
  power results in prolong battery life

Availability

 

 

• Three level inverter/rectifier

• The voltage stress of the UPS
  semiconductors is reduced by half,
  thus ensuring prolonged life of the
  critical components

• Replaceable power
  sub-assemblies

• Easy replacement in the event of
  failure significantly reduces the
  Mean Time To Repair (MTTR)

• Intelligent battery management

• Maximizes battery performance,
  life and reliability

• Excellent generator adaptability

• Flexible input performance adjust
  with generator and eliminate
  generator over sizing

Adaptability

 

 

• Common or dedicated battery
  configuration

• Allows the deployment of the cost
  effective common battery
  configuration

• Standard built in LBS and smart
  parallel function

• Ensure trouble free installation
  and commissioning

• Power walk-in enabled

• Progressively transfer load on
  generator

• Integrated transformer option

• Makes Liebert NX compatible with:
   - Medical and other critical
     applications
   - Installation with two independent
     input sources
   - Installation in distribution without
     neutral.

• Flexible to accommodate inbuilt
  battery back up

• No need for external battery
  rack/cabinet

• Configured to deliver single or
  three phase power
