    Tips:
    Please buyers know the module usage method and electronic professional knowledge before buying.
    Note:
    For the sake of safety, please try to leave some margin,consider the maximum value of the voltage when the
    battery is full.The output voltage must not be transferred to more than 35V.Output power as far as possible not more
    than 10W.Over the need to add heat please
    Module parameter:
    1.Input voltage: 5-57V
    2.Output voltage: 1.25-30V(Delivery voltage:4.2V; current:1A)
    3.Low dropout voltage: Input voltage must be higher than the output voltage 2V, can not boost
    4.Output current: 12V to 5V,max 3A (other Output voltage:current=15/output voltage)
    5.Output power: 15W (If the temperature is high, please install the heat sink)
    6.Conversion efficiency: 80%
    7.Working temperature: Industrial grade -40℃ to +85℃ (Ambient temperature exceeds 40 degrees, please reduce the
    power to use, or to enhance the heat)
    8.Full load temperature rise: 45℃
    9.No-load current: 10mA (48V to 4.2V)
    10.Potentiometer adjustment direction: Clockwise (increase), counter clockwise (decrease)
    11.Working indicator: Double color indicator light, charging indicator light red, charging end indicator light green
    (not connected to the load is green)
    12.Module size: 48*24*11.4mm(L*W*H)No potentiometer (Potentiometer high 13mm)
    13.Output short circuit protection: Yes.constant current
    14.Input reverse connection protection: Yes
    15.Constant current range: 0.2-3A (Adjustable, by default to 1A)
    16.Turn lamp current: Constant current value*(0.1)
    Application:
    1.As a battery charger
    (1)Make sure you need to charge the battery float voltage and charging current and the input voltage of the module.
    (2)Adjust the constant voltage potentiometer, the output voltage is adjusted to about 5V.
    (3)with a multimeter to measure the output current range 10A short circuit current ( directly to the two leads can
    be connected to the output ), while adjusting potentiometer allows constant output current reaches a predetermined
    charge current value.
    (4)Adjust the potentiometer to the output voltage to constant float voltage.
    (5)connected to the battery charge.
    ( 1,2,3,4 steps : input termination power output of the load is not connected to the battery )
    2.As LED constant current driver module
    (1)determine the work that you need to drive the LED current and maximum operating voltage ;
    (2)Adjust the constant voltage potentiometer, the output voltage is adjusted to about 5V;
    (3)10A current with a multimeter measuring the output short-circuit current file, and adjust the constant current
    potentiometer allows the output current reaches a predetermined LED working current;
    (4)Adjust the potentiometer to make the output voltage reach the maximum working voltage of LED'
    (5)connected to the LED, test machine.
    ( Step 1,2,3,4: input connected to the power supply , the output load is not connected LED lights. )
