Figure 66: Constant voltage mode
Crossover from the constant-voltage mode to the constant-current mode also occurs automatically in
response to an increase in load. For example, connect a 5 Ω resistor to the binding posts on the front
panel, set the voltage to 25 V and current limit to 1.0 A, and turn on the output. The power supply is
operating in CC mode. For details, refer to the following figure.
