            Some Applications:

    • High-power LED constant current driver.
    • Lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charge.
    • Solar panels, wind generator voltage regulator circuit board power supply, such as automatic buck regulator circuit.

            Battery use:

    • Make sure of the voltage and current of the battery you need to charge
    • Adjust the constant voltage potentiometer to make sure the output Voltage is about 5V(about).
    • 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
    • The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
    • Adjust the constant voltage potentiometer to make sure the output Voltage is up to floating Voltage.
    • Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries).

            LED Constant Current Driver Use:

    • 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 5V(about).
    • 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.
    • Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage.
    • Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED).
