TypicalLEDpowersupplyI-Vcurve
A typicalLEDpowersupplymayeitherworkin"constantvoltagemode(CV)orconstantcurrentmode(CC)"todrivetheLEDs.
Mean Well's LED power supply with CV+ CC characteristic can be operated at both CV mode (with LED driver, at area (A) and CC mode (direct drive, at area (B).
