Local Operation
3-12 M370430-01 Rev E
Output disabled The mode of operation is not determined until the output is enabled. The
CV and CC mode LEDs will not indicate the mode while the output is
disabled.
Constant Voltage (CV) Mode Operation
If the output is enabled and the configured current set point is much
higher than the requirements for the attached load, then the voltage will
rise until it reaches the voltage set point. When the output voltage
reaches the voltage set point, it stops rising. The unit will continue to
operate in CV mode. The load current will still vary to meet any changes
in required load current draw resulting from a change in the attached
load.
Constant Current (CC) Mode Operation
If the output is enabled, the voltage and current start to rise. At this time
the unit is operating in CV mode (default operational mode). As the load
current drawn reaches the value of the output current setting, the unit
will switch to CC mode and not allow any additional current to be drawn
above the value of I
SET
. The unit is now operating in CC mode. The
voltage will still vary to meet any changes in required output voltage
resulting from a change in the attached load.
Constant Power (CP) Mode Operation (version 2.21 and higher)
If the output is enabled, the voltage and current start to rise. The unit
will continue to increase the current until one of thefollowing occurs:
•
The programmable power set point has been reached.
•
The voltage set point has been reached, in which case the unit will
regulate the voltage in order to maintain the voltage set point.
•
The current set point has been reached, in which case the unit will
regulate the current in order to maintain the current set point.
