5.5. Regulation States

The DBx Module has three regulation states: Constant Voltage (CV), Constant Current (CC), and Constant Power (CP). The active regulation state is indicated by a illuminated circular LED next to the respective voltage, current, power, or resistance set-point button. The active regulation state can also be monitored programmatically.

5.5.1. Constant Voltage (CV)

When the constant voltage regulation state is indicated, the Accessory is maintaining fixed voltage set-point, while the current flucuates with the driving DC source, as illustrated by Fig. 5.7.

5.5.2. Constant Current (CC)

When the constant current regulation state is indicated, the Accessory is maintaining a fixed current set-point, while the voltage fluctuates with the driving DC source, as illustrated by Fig. 5.8.

5.5.3. Constant Power (CP)

When the constant power regulation state is indicated, the Accessory is maintaining a fixed power set-point by varying the current level inversely in response to a change in input voltage, as illustrated by Fig. 5.9.
