CV/CC Crossover Characteristics
Background
The RPE-1326/2323/3323/4323 series automatically switch
between constant voltage mode (CV) and constant current mode
(CC), according to load condition.
CV mode
When the current level is smaller than the output setting, the
RPE-1326/2323/3323/4323 series operates in Constant Voltage
mode. The CV indicator for the corresponding channel appears
on the LCD. The Voltage level is kept at the setting and the
Current level fluctuates according to the load condition until it
reaches the output current setting.
CC mode
When the current level reaches the output setting, the RPE-
1326/2323/3323/4323 series starts operating in Constant Current
mode. The CC indicator for the corresponding channel appears
on the LCD. The Current level is kept at the setting but the
Voltage level becomes lower than the setting, in order to
suppress the output power level from overload. When the current
level becomes lower than the setting, the RPE-
1326/2323/3323/4323 series goes back to the Constant Voltage
mode.
