Application:
1. Use as a step-down modules with over current protection capabilities:
-Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
-Use a multi meter (set on 10A) to measure the output short-circuit current, while regulating the “current potentiometer” so that the output current reaches a predetermined over current protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)
-Connected to the load.
2. Use as a battery charger:
-Determine the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
-Without battery connected, adjust the “Voltage potentiometer” so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
Use a multi meter 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.
-While charging, the battery current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged)
3. Use as a LED constant current driver module:
-Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
-Use a multi meter (set on 10A) to measure the output short-circuit current, while regulating the “current potentiometer” so that the output current reaches a predetermined LED operating current.
-Connect LED, work.
