Adaptive light current: when matched with a light source with adaptive function, the controller can identify the current of the light and automatically adjust the maximum output current；
Power on self-test mechanism: when the adaptive function is turned on, the controller will automatically detect the light status (short circuit, open circuit, overload) when entering the adaptive mode, turning on, and replacing the light source. After detecting no abnormality, the controller will enter the normal working state；
Adaptive mode off, channel current adjustable.
