Button/Potentiometer/LED introduction:
1>.Long press means need keep press for more than 3second.
2>.Button ON:Short press to turn ON or OFF output voltage.Long press is used to turn ON or OFF screen meanwhile voltage keep output.
3>.Button SW:Short press to switch display output voltage,output current or display these parameters in turn.Long press is used to enter or exit calibration mode.
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.
6>.V LED:Red indicator.It will turn ON when display output voltage.
7>.A LED:Blue indicator.It will turn ON when display output current.
8>.Input terminal:There are three input methods:
8.1>.Method 1:Standard Type A USB Male .It just can input DC 5V.
8.2>.Method 2:Micro USB Female.It just can input DC 5V.
8.3>.Method 3:IN+ and IN- pads.It can input DC 3.5V-12.0V.
8.4>.It can only choose one input method.
9>.Output terminal:KF-301-2P 5.08mm blue terminal. It can output DC 1.2V-24.0V.

Note:
1>.It is a DC power module,So it can not connect to AC power.
2>.Please don’t short output.
3>.’IN-’ and ‘OUT-’ can not be connect together,otherwise module can not support constant current output.
4>.Please make sure input power is more than load power.
5>.Please step down output power if module is hot.
6>.Rotate CV potentiometer counterclockwise more than 10 turns if the output voltage can not be adjusted.
7>.Output current can not keep a fix value output.It changes with load.But output power can not exceed 3W.
8>.Please read use manual and description before use.

Application:
1>.Ordinary power supply;
2>.Instrument voltage display;
3>.Test meter;
4>.Circuit test;
5>.Power conversion.
