  • According to the form of output power
    • For single-phase output, input is single-phase or three-phase.
    • For three-phase output, input is three-phase or single-phase.
  • According to the electrical architecture
    • Standby UPS also refers to offline UPS
    • Line interactive UPS
    • Double conversion UPS also refers to online UPS
  • According to backup time
    • Standard with battery
    • Can work with external EBM to get longer backup time
  • According to the fact that whether there is an industrial frequency transformer
    • The rectifier transformer steps up voltage also referring to industrial frequency UPS
    • Without rectifier transformer, also refers to high frequency UPS
  • According to the installation method
    • Tower type
    • Rack type
    • Tower/Rack type
  • According to the configuration method
    • Traditional UPS (standard)
    • Modular UPS (configuration)

Standby (offline) UPS

  • For small capacity (<2KVA), single phase UPS
  • Simple structure
  • The backup battery mode generally has a square wave output

 

 Line interactive UPS

  • For small capacity (<3KVA), single phase UPS
  • Capable of compensating AC abnormal high and low voltage changes (AVR)
  • The backup battery mode generally has a square wave or sine wave output

Online UPS

  • Capacity of 1-200KVA and above, single/three-phase UPS
  • Ability to perform power factor correction (PFC) function
  • Double conversion
  • Sine wave output
