CV/CC Crossover Characteristics
Background
The T3PSX3200 series automatically switches 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 T3PSX3200 series operates in Constant
Voltage mode. The 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
T3PSX3200 series starts operating in Constant Current
mode. The 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 T3PSX3200 series goes back to the
Constant Voltage mode.
