    3. Operation 3.1 General C³V Series integrates two power supplies – constant voltage (CV) and constant current (CC). These two power supplies exclusively operate, and outputs do not exceed user-preset limit. CV or CC states are dependent on and limited by the comparison between load conditions and C³V Series settings.
