4.1 Set the Output Priority Mode

This series instrument can set the output priority mode like CV priority or CC

priority.

•

The following figure shows the CV/CC priority operating locus of the output. The

area in the white quadrants shows the output as a source (sourcing power). The

area in the shaded quadrants shows the output as a load (sinking power).

CV priority mode:

Voltage priority mode keeps the output voltage constant. In voltage priority

mode, the output voltage should be set to the desired value. A positive and

negative current limit value should also be set. And the output is controlled

by a constant-voltage feedback loop, which maintains the output voltage at

its programmed setting as long as the load current remains within the

positive or negative current limit settings.

Current priority mode keeps the output current constant. In current priority

mode, the output current should be programmed to the desired positive or

negative value. Voltage limit range should also be set. And the output is

controlled by a bi-polar constant current feedback loop, which maintains the

output source or sink current at its programmed setting. The output current

remains at its programmed setting, provided the load voltage remains within

the voltage limit setting.
