Instructions:
The module output should not short circuit or measure the current directly with a multimeter short circuit, a short circuit will burn the module. Adjustable low voltage range: DC10V-50V (clockwise to increase, counterclockwise to decrease), first set the undervoltage to the minimum, then set the input voltage to the required undervoltage protection value, slowly adjust the undervoltage value clockwise to increase it; when the low voltage voltage voltage is under voltage indicator lights , set it around a circle counterclockwise and then turn it on again. Input undervoltage protection is mainly used to prevent deep discharge of the battery when the input power source is a battery. Low battery voltage damages power module and battery. If the input is a switching power supply, the low voltage protection must also be adjusted. Constant voltage adjustment range: DC12-97V (clockwise to increase, counterclockwise to decrease), first set the voltage to the required voltage and then connect to the load.Constant current adjustment range: 0.8-22A (clockwise to increase and counterclockwise to decrease), first disconnect the load, then set the output voltage to the required voltage, set the current to the minimum (turn CC potentiometer counterclockwise by about 30 circles), an A. mperemeter in Row switch to the output, then slowly adjust the current (booster module cannot adjust the current directly by short circuit)The input voltage should not be lower than 10V or higher than 60V (if the input voltage is lower than 12V, please reduce the load correctly). that the Input voltage is at least 2 V lower than the output voltage. If you use a switching power supply or other secondary power supply, please make sure that the power is at least 1.3 times higher than the power of the power supply module. During overcurrent or undervoltage protection, the output still has a voltage. the near of the E, the Einput voltage, protection means no boosting voltage.
