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.
