An app note from Alpha and Omega Semiconductor on importance of start-up power behavior to diagnose and prevent unwanted inrush current. Link here (PDF)
Electronic loads, such as Chroma 6310 series, can be configured as constant current (CC) mode, constant voltage (CV) mode and constant resistance (CR) mode. In CC mode, the load will sink a current in accordance with the programmed value regardless of input voltage. In CV mode, the load will sink current to control the voltage source in programmed value. In CR mode, the load sinks a current linearly proportional to the input voltage in accordance with the programmed resistance. Internal feedback control circuit controls the load current based on its mode set up and input voltage.
