1. Make sure of the battery float voltage and charging current that you need, the input voltage of the module.
2. Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value.
3. Adjust the constant voltage potentiometer make the output voltage reaches the float voltage;
4. Connected to the battery, try to charge.
(1,2,3,4 steps to connect the power module input, output no-load does not connect battery.)
LED constant current drive:
1.Make sure operating current and Max operating Voltage of the LED you need to drive.
2.Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3.Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected LED operating current.
4.Adjust constant voltage potentiometer make the output voltage reach the maximum LED operating voltage.
5.Connect LED, test.
(1,2,3,4 steps to connect the power module input, output No-load does not connect LED.)
