Power Supply Function
In CV priority mode, the output voltage should be programmed to the desired
value. A positive and negative current limit value should also be set. The current
limit should always be set to a value that is greater than the actual input current
requirement of the external load. The following figure shows the CV priority op-
erating 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).
In sink mode, there is a minimum operating voltage. The minimum operating
voltage specification data corresponding to different voltage models are as
follows.

ing Voltage (MOV)
