What is a UPS?

A UPS is an electrical apparatus that provides clean electricity protection to electrical equipment againstmains power fails and power disturbances.

A UPS is an electrical protection system in case of power failure, it will protect your equipment against overvoltages, voltages and free interruptions.


Different type of UPS:


  • First generation versions
  • Switches to the standby circuit (batteries)
  • Long switching time < 6ms
  • Does not regulate voltage


Line Interactive

  • Intelligent inverters
  • Micro-processor controlled system
  • Switching time < = 2ms
  • Regulates voltage
  • Simulates a perfect sine wave output


  • Basic protection

  • Switching time

  • Power factor between 0.4 and 0.6

  • Single-phase input (220 volts)

  • Single-phase output (220 volts)

  • Option: stop the software (ex: IP Pro Evolution)

  • Full load autonomy 5 to 7 minutes




How does a line-interactive UPS function?























  • Regulates voltage
  • No switching
  • Double conversions
  • Almost perfect reactivity
  • Pure and perfect sine-wave output
  • Optimum protection
