ADJ-I is the current setting potentiometer. Rotate clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, and the CC constant current indicator (red) lights up. The OUT indicator is an output status indicator, which lights up when there is voltage at the output terminal, otherwise it is off; the CHAR indicator is a charging indicator, which lights up when charging, and the FULL indicator is a full indicator. If the set constant current value is 2A, charge When the current reaches below 0.2A, the lamp will turn on, the FULL indicator will be on, and the CHAR indicator will be to use:
(1) Press the button to set the output voltage to reach the voltage value you want.
(2) First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then use a multimeter to measure the output short-circuit current at 10A current range (directly connect the two test leads to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise Make the output current reach the overcurrent protection value you want to set. (For example, the current value displayed by the multimeter is 2A, then the maximum current when you use the module can only reach 2A, when the current reaches 2A, the red constant current indicator light is on, otherwise the indicator light is off)
The module without constant current function cannot be used to charge the battery. Because the voltage difference between the exhausted battery and the charger is very large, the charging current is too large and the battery is damaged. Therefore, the battery must be constant at the beginning. Current charging, when the charging reaches a certain level, it will automatically switch back to constant voltage charging.
(1) Determine the floating voltage and charging current of the rechargeable battery you need; (If the lithium battery parameter is 3.7V/2200mAh, then the floating voltage is 4.2V and the maximum charging current is 1C, which is 2200mA)
(2) Under no-load conditions, the button output voltage reaches the float voltage; (if charging a 3.7V lithium battery, adjust the output voltage to 4.2V)
(3) First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then use a multimeter to measure the output short-circuit current at the 10A current range (directly connect the two test leads to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise Make the output current reach the predetermined charging current value;
(4) Connect the battery and charge it.
(When setting steps 1, 2, and 3: the output terminal is not connected to the battery without load)
(1) Determine the operating current and maximum operating voltage you need to drive the LED;
(2) Under no-load conditions, press the button to set the output voltage to reach the highest LED operating voltage;
(3) First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then use a multimeter to measure the output short-circuit current at the 10A current range (directly connect the two test leads to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise Make the output current reach the predetermined LED working current;
(4) Connect the LED and test the machine.
(When setting steps 1, 2, and 3: output no-load without LED includes:1 xDC Buck Module
Note:
1. Module input IN- must not be short-circuited with output OUT-, otherwise the constant current function will fail.
2. Please make sure that the power of the power supply is always greater than the power required by the output load. Please reduce the power when the module is seriously hot!
