DC-DC CVCC 15W 2A Voltage Step Up and Step Down Regulator

Button/ Potentiometer / LED introduction

• Long press means it must be pressed for more than 3 seconds.
• Left Button: ON / OFF button. Short press is used to turn the output voltage ON or OFF in display mode or 'Minus -' in calibration mode or trigger fast charging in fast charge protocol selection mode. For next re-power in display mode or OFF
• Right Button: SELECT button. Press to change the display output voltage, output current, output power, or display these parameters sequentially in display mode, or show as 'Plus +' in calibration mode, or start fast charging in fast charging protocol selection mode. Used to enter or exit calibration mode.
• CV Potentiometer: Adjust the output voltage. Increase the output voltage while rotating clockwise. If the output voltage cannot be adjusted, turn the CV potentiometer 10 counterclockwise.
• CC Potentiometer: Adjust the output current. Increase the output current while rotating clockwise. Note: It does not maintain a constant output current. When the load current reaches the set current value, the module starts to stabilize this current value. When you set the short circuit output terminal output current.
• ON LED: Green Output indicator. It turns ON when there is an output at the output terminal. Otherwise, it is OFF.
• CC LED: Red Constant current output indicator. It enters the constant current state when the load current reaches the set current and the CC constant current indicator is ON.
• FC LED: Blue Fast charge indicator.
• Input terminal: There are three input methods:
•       Method 1: standard type A USB male. It can only input DC 5V.
•       Method 2: Micro USB Female. Only DC 5V can enter.
•       Method 3: DC 4.0V-13.0V via IN+ and IN- ports      Can only choose one input method.
• Output terminal: 5.08mm blue terminal. It can output DC 0.5V-30.0V.
