Instructions:Module output should not short circuit or measure current directly  with multimeter short circuit, short circuit will burn out module.Under voltage adjustable range:DC10V-50V (clockwise to increase, counterclockwise to reduce), firstly adjust under-voltage to the minimum, then adjust input voltage to required under-voltage protection value, slowly adjust under-voltage value clockwise to increase; when the under-voltage light is on, adjust counterclockwise of one circle, then power on again. Input under-voltage protection mainly used to prevent battery from over-discharging when input power source is battery. Low battery voltage will damage power module and battery. When input is switching power supply, it also need to set the low voltage protection.Constant voltage adjustable range:DC12-97V(clockwise to increase, counterclockwise to reduce), first adjust voltage to the required voltage and then connected to the load.Constant current adjustable range:0.8-22A (clockwise to increase and counterclockwise to reduce), first disconnect load, then adjust output voltage to required voltage, adjust current to the minimum (counterclockwise turn CC potentiometer about 30 circles), connect an ammeter in series to the output, then slowly adjust current.(booster module cannot directly adjust current by short circuit)Input voltage should not be lower than 10V or higher than 60V, (when input voltage is lower than 12V, please properly reduce the load).Make sure the input voltage is at lease 2V lower than output voltage. If use switching power supply or other secondary power supply, please make sure that power is 1.3 times greater or more than the power supply module's power.During over current or under-voltage protection, output will still have voltage that is close to the input voltage, protection means no boosting voltage.
