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).
