IPS X303 Series Instruction Manual

CV/CC Crossover Characteristics
The IPS X303 series automatically switches between constant voltage
mode (CV) and constant current mode (CC), according to load condition.
When the current level is smaller than the output setting, the IPS X303
series operates in Constant Voltage mode. The indicator on the front
panel turns green (C.V.) 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.
When the current level reaches the output setting, the IPS X303 series
starts operating in Constant Current mode. The indicator on the front
panel turns red (C.C.) 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 IPS X303 series goes back to the Constant Voltage
mode.
