Hey Linden,
For reference this is the product page link.
DC-DC Adjustable Step-down Module 5A 75W
CC = Constant current or current limit.
CV = Constant voltage or voltage regulation
As Bob mentioned before, to adjust the output limits with the potentiometers keep in mind “the adjustment knobs are 30-turn potentiometers that control the voltage and current limits. This means you may have to turn them up to 30 turns to get from the top of the output limit range (36V) to your target voltage.”
Hope this summary helps!
