Output Function

The heavy solid line illustrates the locus of possible operating points as a

function of output. As shown by the horizontal portion of the line, the output

voltage remains regulated at its programmed setting as long as the load current

remains within the positive or negative current limit setting. A CV status flag

indicates that the output voltage is being regulated and the output current is

within its limit settings.

Note that when the output current reaches either the positive or negative

current limit, the unit no longer operates in constant voltage mode and the

output voltage is no longer held constant. Instead, the unit will now regulate the

output current at its current limit setting.

As shown by the vertical portions of the shaded quadrants, the output voltage

may continue to increase in the positive direction or decrease in the negative

direction as current is forced into or pulled out of the unit. When the output

voltage exceeds the over-voltage protection setting, the output will shut down.
