Alarm Threshold Protection by Default: if the voltage <4.5V or the voltage >13.8V and the current > 5.1A , there would make a alarm and shut off output if the above occurs.(The default alarm threshold protection can be amended according to your specified requirements)
Range of High Voltage Protection Threshold: > 1.0-13.8V; By default, there would be sort of protection if the voltage is greater than 13.8V.
Range of Low Voltage Protection Threshold: <0.5-24V; By default, there would be sort of protection if the voltage is less than 4.5V.
Range of Over-current Protection Threshold: >0.5A-5.1A; By default, there would be sort of protection if the current is greater than 5.1A.
