Product overview
C6027 20 Version: 1.1
3.6 1-second UPS
NOTE
Loss of data
The use of the 1-second UPS outside of the documented possibilities can lead to loss or corruption of data.
• Use only TwinCAT to control the 1-second UPS and save only persistent data with a maximum size of 1
MB.
There is an option to order the Industrial PC with an internal uninterruptible power supply (UPS). This is a
capacitive 1-second UPS for the reliable saving of persistent application data on the storage medium.
TwinCAT and Windows IoT Enterprise are required for this.
You can order the Industrial PC ex-factory with an internal UPS under the order designation C9900-U334.
The capacitive 1-second UPS continues to supply the processor with power if the power supply fails. During
this period persistent data can be saved, which are available on switching on again. Since the capacity of the
1-second UPS is neither sufficient for bridging power failures nor for operating a hard disk, in the event of a
power failure the data is only stored on the Compact Flash/CFast/MicroSD card. The 1-second UPS only
works for a few seconds.
