Button/Potentiometer/LED introduction:
1.Long press means need keep press for more than 3second.
2.Left Button:Long press is used to set default ON or OFF for next re-power at display mode or as ‘Minus -’ in calibration mode.Short press to select whether output voltage at display mode.
3.Right Button:Long press is used to enter or exit calibration setup mode at display mode or as ‘Plus +’ in calibration mode.Short press to switch display output voltage,output current, output power or display these parameters in turn.
4.CV Potentiometer:Adjust output voltage.Increase the output voltage when rotating clockwise.Please rotate the CV potentiometer 10 turns in counterclockwise if the output voltage cannot be adjusted.
5.CC Potentiometer:Adjust output current.Increase the output current when rotating clockwise.Note:It is not keeping a fixed output current.When the load current reaches the set current value, the module starts to fix output this current value.
6.ON LED:Green Output indicator.It will turn ON when there is a output at output terminal.Otherwise it is OFF.
7.CC LED:Red Constant current output indicator.It enters the constant current state when the load current reaches the set current and CC constant current indicator turns ON.

Input terminal:There are three input methods:
Method 1:Standard Type A USB Male .It just can input DC 5V.
.Method 2:Micro USB Female.It just can input DC 5V.
Method 3:IN+ and IN- pads.It can input DC 4.0V-13.0V.

.Method 2:Micro USB Female.It just can input DC 5V.
Method 3:IN+ and IN- pads.It can input DC 4.0V-13.0V.
It can only choose one input method.
Output terminal:
KF-301-2P 5.08mm blue terminal. It can output DC 0.5V-30.0V.
Protective function:
Over-Voltage Protection:Module will turn OFF output voltage automatically if output voltage is more then 30.5V.
Over-Current Protection:Module will turn OFF output automatically if output current is more then 2A.
Over-Power Protection:Module will turn OFF output automatically if output power is more then 15W.It will display ‘-OP-’.User need reduce load power and then press ‘ON/OFF’ button.
Current error:Large display error when output current is less than 0.05A.It can not display output current if current is 10~40mA.
Over Temperature Protection:Module will turn OFF output automatically if termperature is more then 100℃.It will display ‘-OT-’.User need reduce load power and then press ‘ON/OFF’ button.
Note:
1.It is a DC power module,So it can not connect to AC power.
2.Please don’t short output.
