Best-in-class Efficiency

  • Supports parallel operation up to 4 units N+X confi guration
  • Backup time can be prolonged through cascaded connection or use of large capacity battery bank
  • Outstanding energy-saving performance with more than 92% efficiency
  • Input power factor of up to 0.99 with high electric energy utility rate
  • Extra-wide input voltage / frequency range effectively reduces the discharging period of battery; thus, prolonging battery life
  • Compatible with single-phase and 3-phase input power
  • Optional strong charging capability effectively reduces battery recharging time

Highly Reliable

  • Double-conversion online design that ensures continuous power even when the mains AC fails
  • Supports N+X redundant mode up to 4 units for increased system reliability
  • DSP full-digital control with high output voltage precision
  • Uses state-of-the-art technology and components to withstand fl uctuation of input main voltage
  • Provides latest USB monitoring interface
  • Optional WEB / SNMP card for remote management
  • Available in standard and long backup for 4 to 8 hours runtime. External charger is also available

Best Total Cost
