Note 
The power supply contains an active PFC (Power Factor Correction) circuit to conform to the 
EMC guidelines. 
 
Uninterruptible AC power systems (UPS) must supply a sinusoidal output voltage in the 
normal and buffered mode when u
sed with SIMATIC PCs with an active PFC. 
UPS characteristics are described and classified in the standards EN 50091
-3 and IEC 
-3. Devices with sinusoidal output voltage in the normal and buffered mode are 
identified with the classification "VFI
-SS-...." or "VI-SS-....".
