DC-DC 15W Voltage Booster and Stepper Regulator Module
It is a voltage booster and stepper module with a 7-segment display. You can view the output voltage, output current and output power on the screen. The output voltage and current can be adjusted by potentiometers on it. It can be used as a normal power supply module, charger and LED constant current driver.
Button/ Potentiometer / LED introduction:
- Long press, more than 3 seconds means it should be kept pressed.
- 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.
