Button/Potentiometer/LED Introduction:

  1. Long press: Press and hold for more than 3 seconds.
  2. ON/OFF: Short press to select the output state; long press to restore default settings.
  3. IN/OUT: Short press to switch between displaying input voltage or output voltage; long press to switch between displaying output current or output power.
  4. CV Potentiometer: Adjusts the output voltage; rotate clockwise to increase the output voltage.
  5. CC Potentiometer: Adjusts the output current; rotate clockwise to increase the output current.
  6. ON LED: Green LED that indicates the presence of output at the output terminal.
  7. CC LED: Red LED that indicates constant current output; turns on when the load current reaches the set current value.

Can be used as:

1.As an ordinary step-up power module.

2. As a charger:

1. Note that the power module can only be used as a charger if it supports constant current functionality. It’s crucial to maintain constant current charging to avoid excessive charging current and potential battery damage.

2. Determine the floating charge voltage and charge current suitable for the battery. For example, if the lithium battery has parameters of 3.7V/2200mAh, the float charge voltage should be set at 4.2V, and the maximum charging current should be 1C, which is 2200mA.

3. Connect the correct input voltage to the input terminal. (Ensure no load is connected during parameter setting).

4. Test the output voltage using a multimeter and adjust the CC potentiometer to ensure the output voltage matches the required floating charge voltage (e.g., 4.2V for charging a 3.7V lithium battery).

5. Rotate the CC potentiometer counterclockwise for more than 10 turns initially.

6. Test the output short circuit current using a multimeter set to 10A or 20A by connecting the test probes to the module’s output terminal.

7. Rotate the CC constant current potentiometer clockwise to set the desired output current according to the required charge current value.

8. Connect the battery to the output terminal and commence charging.

3. As a high-power LCD constant current driver.

Note:

  1. The input undervoltage protection voltage is set at 4.7V. The module needs to be re-powered if the input voltage falls below this threshold.
  2. If there is no output voltage, rotate the CV potentiometer counterclockwise for more than 20 turns.
  3. This module is designed for DC power only and cannot be connected
