J5019 Hw 357: Versatile Li-ion Charger And Boost Module For a Wide Range Of Applications

4A Buck Boost Converter Module Adjustable Step Up and Step Down Function with LCD Display Power (HW-140) Function Description: The module has IN/OUT, ON/OFF two buttons: IN/OUT button switches input voltage and output voltage display, long press can switch output current output power display; ON/OFF button control output ON or OFF, long press can Set the default output status of the next power-on to be ON or OFF. CC is the current setting potentiometer, clockwise rotation, can increase the set current, when the load current reaches the set current, enter the constant current state, the CC constant current indicator (red) lights up; the right CV is the voltage setting The potentiometer rotates clockwise to increase the output voltage. The ON indicator is an output status indicator that lights up when there is voltage at the output, otherwise it is off. Instructions: 1. Use as a common buck-boost module with overcurrent protection (1) Adjust the CV constant voltage device so that the output voltage reaches the voltage you want. (2) Use the multimeter 10A current file to measure the output short-circuit current (directly connect the two test leads to the output terminal), and adjust the CC constant current potentiometer to make the output current reach the predetermined overcurrent protection value. (3)(For example, if the current value displayed by the multimeter is 2A, then the maximum current can only be 2A when you use the module, and the red constant voltage constant current indicator will be on when the current reaches 2A, otherwise the indicator will be off) Note: When using in this state, there is a current sampling resistor at the output, there will be a voltage drop of 0~0.2V after the load is connected, and at the same time, the input wire and the output wire will have a certain line voltage drop when the current is large. This is normal! 2. Use as a battery charger Modules without constant current function cannot be used to charge the battery. Because the voltage difference between the battery and the charger that consumes electricity is too large, the charging current is too large, causing damage to the battery. Therefore, the battery should be used at the beginning. Stream charging, automatically switch back to constant voltage charging when charging to a certain extent electronicstore.pk
