1-second UPS

Notice

Loss of data

Using the 1-second UPS in a way that is not documented as an option can lead to loss or corruption of data.

  • Only use TwinCAT to control the 1-second UPS and only save 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 reliable saving of persistent application data on the storage medium. This requires TwinCAT and Windows Embedded Compact 7.

You can order the industrial PC with internal UPS ex factory by specifying the order identifier C9900-U213.

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 when the device is switched 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.
