have a constant ( controlled ) Output Voltage.
But there are also "bench" "lab" power supply what have a adjustable Voltage
but for some usage you need a constant current 'CC' ( with a variable Voltage )
like LED driver and battery charger...
then it would ( automatically ) have a CV mode and a CC mode, depending on the load and CV, CC adjustments.
in that case that current could be also adjustable, like by a POTI

try FydeOS
