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).

Package Included: 1x DC-DC Step Down Voltage Converter
