Preventing potential failures...
...with uninterruptible power supplies (UPS)
Electrical devices and systems malfunction in the presence of
supply disturbances such as variations in voltage or frequency,
short interruptions, or grid failure. In the case of data processing
equipment, this can often lead to processing errors, data
loss, and in the worst case to lasting damage to both software
and hardware. The power supply unit fitted to the SIMATIC PC for tough
industrial requirements bridges voltage failures lasting up to
20 ms (NAMUR).
If longer voltage failures are to be bridged, an uninterruptible
power supply (UPS) is needed. This will maintain the supply
long enough for the system to be shut down properly.
The SITOP and Masterguard uninterruptible power supplies
are available for applications that must work non-stop when
the power fails, providing 24 V DC or 115/230 V AC or integrated,
customer-specific UP supplies.
