The total output of the +5 V and +3.3 V voltage must be ≤ 190 W.
The inrush current is:
● ≤ 80 A for 3.6 ms
Note
Operation on an uninterruptible power supply (UPS)
The power supply contains an active PFC (Power Factor Correction) circuit for adherence to
the EMC guidelines.
Uninterruptible power supplies must supply a sinusoidal output voltage in normal and
buffered mode when used with SIMATIC IPCs with an active PFC.
The characteristics of uninterruptible power supplies are described and classified in the
standards EN 50091-3 or IEC 62040-3. Devices with sinusoidal output voltage in normal and
buffered mode are identified with the classification "VFI-SS-...." or "VI-SS-....".
