Lithium battery charger
Solar panels and wind turbines.
Typical Application:
Using for LED constant current driver:
Make sure operating current and Max operating Voltage of the LED you need to drive.
Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage.
Use the multi meter 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.
Connect LED then test again with above sequent (1,2,3,4 steps to connect the power module input and output load does not take LED.)
Using for Battery:
Make sure of the voltage and current of the battery you need to charge.
Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
Use the multi-meter 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.
Charge transfer lamp current default value is 0.1 times of the charging current(constant current value)
For lamp current adjustment, please turn potentiometer adjustment;
Connect battery and trying charge up. (1,2,3,4 steps to connect the power module input and output load does not take batteries.)
