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.
