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.
8>. 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.
● It can only choose one input method.
9>. Output terminal: KF-301-2P 5.08mm blue terminal. It can output DC 0.5V-30.0V.
Note:
It is a DC power module,So it can not connect to AC power.
Please don’t short output.
'IN-' and 'OUT-' can not be connect together,otherwise module can not support constant current output.
Please make sure input power is more than load power.
Please step down output power if module is hot.
Rotate CV potentiometer counterclockwise more than 10 turns if the output voltage can not be adjusted.
Output current can not keep fix value output.It changes with load.But It can not exceed set output current value.
There is a protective film on the surface of the shell. It is recommended to tear it off for a clearer effect.
Please read use manual and description before use.
