1-second UPS: Securing important data in case of power
failure
This application example describes the advantages of using UPS-assisted Industrial PCs on the basis of
three exemplary applications. As an ‘on-board UPS,’ the capacitor-assisted 1-second UPS from Beckhoff is
very compact, inexpensive and maintenance-free due to the low power consumption of the Intel® Atom™
based motherboard. If a UPS of several minutes duration is not needed, the capacitor performance is
sufficient in many applications to save important data before the IPC switches itself off.
Uninterruptible power supply (UPS)
In the event of a power failure, a UPS creates time for saving important data from the main memory to non-volatile memory.
Depending upon the version, a UPS bridges the power supply for a longer period. External rechargeable battery packs installed
close to the PC are often used.
On-Board-USV
Due to the low power consumption of the Intel ® Atom ™ based motherboard, Beckhoff offers an ‘on-board UPS’ that is very
compact, inexpensive and maintenance-free. Since the ‘1-second UPS’ is also fully integrated into TwinCAT, the customer
has the same advantages as with a regular UPS, but at a lower cost. The time that can be bridged varies according to the
motherboard: depending upon the board, it remains operational for several seconds following a power failure. The relevant
data must be saved during this time. It was possible to save a maximum of 128 KB data with the NOVRAM; at least 1 MB data
can now be saved with the capacitive 1-second UPS.
