This is called "constant voltage" (CV) operation: the '''C.V.''' LED is lit when operating in this mode. If the current needed to stay at the voltage limit is greater than the current limit,
then the supply operates in "constant current" (CC) mode instead, and the '''C.C.''' LED is lit instead of '''C.V.'''. In CC mode, the supply holds current constant at the current limit
and allows voltage to vary. Thus, it's possible to use this supply to provide a constant voltage ''or'' a constant current to a loadwith this supply. To provide constant voltage, set the current limit higher
than the amount of current your load will draw at the intended supply voltage. To provide constant current, set the voltage limit higher than the voltage needed to drive the desired current
through the load.
