On Line technology is identified with the abbreviation VFI (Voltage and Frequency Independent). This technology is commonly called "double conversion". In fact, in mains presence operation, the UPS output is powered by the combination of the rectifier which converts the input voltage of the UPS from alternating to direct and from the inverter which again transforms the direct voltage into alternating. This system ensures that the voltage present at the UPS output is perfectly sinusoidal, clean and very stable both in voltage and in frequency regardless of the problems present on the power supply.
