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.
