3350F Series Operation Manual 97
5-3. Constant Current mode application
The Constant Current (CC) mode is ideal for testing the Load Regulation, Cross Regulation,
Output Voltage and Dynamic Regulation of the power supply under test. The CC mode can
Also be used to test the Discharge Characteristics and the Life Cycle of cells and battery packs.
In CC operation the 3350F can operate as a static load with switchable high and low current
Levels. It is also possible to operate the load dynamically enabling the user to adjust sink
Current with time.
