Constant Voltage Mode
An output channel is operating in Constant Voltage mode when either a load attempts to draw less current than the current limit and the output function is set to NIDCPOWER_VAL_DC_VOLTAGE using the niDCPower_ConfigureOutputFunction function or DC Voltage using the niDCPower Configure Output Function VI, or when the voltage across the load is greater than the voltage limit and the output function is set to NIDCPOWER_VAL_DC_CURRENT using the niDCPower_ConfigureOutputFunction function or DC Current using the niDCPower Configure Output Function VI.
In Constant Voltage mode, the voltage across the output terminals is held constant while the current through the output terminals may change depending on loading conditions. The output channel behaves like a voltage source when in this mode.

Note Constant Voltage mode is synonymous with Voltage-Controlled mode. |
To determine when an output channel is operating in Constant Voltage, use the status indicators on the front panel of the device, the niDCPower Query Output State VI, or the niDCPower_QueryOutputState function.
