APPLICATION:
1. Use as a step-down modules with overcurrent protection capabilities
Use:
(1) Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
(2) Use a multimeter to measure the output short circuit current with 10A stalls, so that the output current reaches a predetermined overcurrent protection value. (For example, the meter shows 4A current value, then you can use the module to maximum 4A current).
(3) load dependent.

2. Use as a battery charger
Use:
(one). Make sure you need to charge the battery float voltage and charging current; (if lithium parameters are 3.7V/2200mAh, float voltage is 4.2V, maximum charging current is 1C, ie 2200mA).
(2). Under no-load conditions, adjust the “voltage potentiometer” so that the output voltage reaches the float voltage; (if it is 3.7V rechargeable lithium battery, the output voltage can be set to 4.2V).
(3). Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined charging current value.
(4). Charging turn lamp current factory default charging current 0.1 times; (during the charging current the battery gradually decreases, if the charging current setting is 1A, then when the charging current is less than 0.1A, the blue lights are off, the green light is on, which means the battery is fully charged).
(5). Depends on battery charge.
(steps 1,2,3,4: output no load, do not connect the battery).

3. Use as LED constant current driver module
Use:
(one). Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
(2). Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined LED operating current.
(3). Connect the LED, work.
(step 1,2: output no load, do not connect LED).
