limits the maximum output voltage. The output voltage is limited to the selected value, irrespective of the values
that have been set at the front panel or at one of the interfaces. The adjustment range is 0 V up to the maximum
rated voltage of the device.
I
limit
limits the maximum output current. The output current is limited to the selected value, irrespective of the values
that have been set at the front panel or at one of the interfaces. The adjustment range is 0 A up to the maximum
rated current of the device.
These settings can only be changed at the display and they apply to all interfaces.

The output is shut immediately if the output voltage exceeds the selected value. The display indicates this status with
the word ‚OVP‘ . To reset this error, push the button

. The OVP value applies to the front panel operation.
There may apply different values for the AI-interface and the digital interface. The digital interface is initialized with
the
value which has been adjusted on the front panel. The adjustment range is 0 V up to the maximum rated voltage
of the 20 %.
