9.6 Protecting against longer power failures

SITOP PSU8200 3ph

Manual, 11.2014, C98130-A7638-A1-2-7629

9.6

Protecting against longer power failures

Sudden and longer failures of the line supply voltage can result in undefined states and

significant danger as a result of the associated failure of the plant or system control. The

SITOP power supply product portfolio includes various DC-UPS solutions to prevent the

failure of the 24 V power supply voltage.
Power supply failures up into the minutes range can be buffered using the maintenance-free

SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-7 24 V buffering to allow

the saving of process data and controlled shutdown of PCs (Page 52)).

Figure 9-7

24 V buffering to allow the saving of process data and controlled shutdown of PCs

Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply

integrated into PC-based automation solutions. This supports further processing of the status

signals and safely running down the PC.
