General
With the overvoltage protection the user can protect the output voltage in case of an unwanted overvoltage at the
VDS200 output in case of wrong voltage setting or failure. The overvoltage protection is a hardware crow bar that
will cut down the voltage output of the VDS 200 and shut down the output voltage.
The overvoltage protection is available at the following devices:
