14.4 AC voltage supply
SIMATIC HMI IPC677C
182 Operating Instructions, 04/2013, A5E02722710-04
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 used with SIMATIC PCs with an active PFC.
UPS characteristics are described and classified in the standards EN 50091-3 and IEC
62040-3. Devices with sinusoidal output voltage in the normal and buffered mode are
identified with the classification "VFI-SS-...." or "VI-SS-....".
