Instructions:
The module output should not measure short circuit or current directly with a multimeter short circuit. The short circuit burns the module.
Under voltage adjustable range: DC10V-50V (to increase clockwise, reduce counterclockwise) first set the undervoltage to the minimum and then set the input voltage to the required undervoltage protection, slowly adjust the undervoltage value clockwise. When the undervoltage light turns on, set counterclockwise of a circle and then insert again.
Input low voltage protection mainly used to prevent the battery from exceeding the input power source. Low battery voltage damages the power module and battery. When the input switches the power supply, the protection must also be adjusted with low voltage.
