Regulation States¶
The DBx Module has four regulation states: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR). 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.
Constant Voltage (CV)¶
When the constant voltage regulation state is indicated, the DBx Module Add-On is maintaining fixed voltage set-point, while the current flucuates with the driving DC source, as illustrated by Fig. 5.1.
Constant Current (CC)¶
When the constant current regulation state is indicated, the DBx Module Add-On is maintaining a fixed current set-point, while the voltage fluctuates with the driving DC source, as illustrated by Fig. 5.2.
Constant Power (CP)¶
When the constant power regulation state is indicated, the DBx Module Add-On 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. 5.3.
Constant Resistance (CR)¶
When the constant resistance regulation state is indicated, the DBx Module Add-On is maintaining a fixed resistance set-point, by sinking input current linearly proportional the input voltage, as illustrated by fig-operating-mode-cr
.
Note
The constant resistance regulation state will only be indicated when the DBx Module Add-On is configured for Resistance Mode.
