UPS operating principles
The system can work as a single unit or parallel one, so as to enhance its reliability
1. AC input filter for filtering input disturbances.
2. Rectifier. To convert AC input voltage into a DC voltage and to increase (boost) the DC
voltage at Inverter.
3. DC/DC Converter (booster): When UPs operates in battery mode, it increase the DC voltage
and supply the inverter.
4. Inverter: to convert the DC voltage into an AC filtered voltage at the output.
5. Bypass: When UPS face an overload or a failure on the inverter, the load is automatically
transferred to Bypass line without any interruption of power to the load.
6. Battery charger: The standard charger feeds the batteries with 1A current. For longer
autonomy times, an optional battery charger at 10A max. is available
7. Battery: VRLA Lead-acid, maintenance-free.
8. Output Filter: to filter the output voltage in order to feed the load with a clean voltage.
9. Maintenance bypass switch is provided so the supply to load will not be interrupted during
repair or maintenance.
