 For example, if the load is such that the power supply is operating in the constant voltage mode, a regulated output voltage is provided. The output voltage remains constant as the load increases, up until the point where the present current limit is reached. At that point, the output current becomes constant and the output voltage drops in proportion to further increases in load. The point is indicated by the front panel LED indicators. The crossover point is reached when the CV indicator goes off and the CC indicator comes on. For example, if the load is such that the power supply is operating in the constant voltage mode, a regulated output voltage is provided.

-Similarly, crossover from the constant current to the constant voltage mode automatically occurs from a decrease in load. A good example of this would be seen when charging a 12-volt battery. ​ll"'​itially, the open circuit voltage of the power supply may be preset tor 13.8 volts. A low battery will place a heavy load on the supply and it will operate in the constant current mode, which may be adjusted for a 1 amp charging rate. As the battery becomes charged, and its voltage approaches 13.8 volts, its load decreases to the point where it no longer·demands the full 1 amp charging rate. This is the crossover point where the power supply goes into the constant voltage mode.+Similarly, crossover from the constant current to the constant voltage mode automatically occurs from a decrease in load.
