127
AC voltage supply
Technical data
IP20 (in installed state)
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-....".
Power supply characteristics
Voltage Nominal 100 - 240 V AC (-15% / +10%), wide
Starting current (load-independent)
Power Good signal of the AC power supply
