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:
Off-Line
- 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
