300W 10A DC-DC Adjustable Buck Converter 7-32V Input, 0.8-28V Output

Module nature: non - isolated step - down constant - current and constant - voltage (CCCV) charging moduleScope of application: high - power LED constant - current driving, lithium - battery charging (including lithium - iron battery), charging of 4V, 6V, 12V, 14V, 24V batteries, charging of nickel - cadmium and nickel - ammonia batteries (battery packs), solar panels, wind turbinesInput voltage: 7 - 32V (5 - 32V without constant current)Output voltage: (1) Continuously adjustable (0.8 - 28V)Product InstructionsBattery Charging - Usage Method:1. Determine the floating charge voltage and charging current of the battery you need to charge, as well as the input voltage of the module.2. Adjust the constant - voltage potentiometer to set the output voltage to around 5V.3. Use the 10A current range of a multimeter to measure the output short - circuit current, and simultaneously adjust the constant - current potentiometer to set the output current to the preset charging current value.4. Adjust the constant - voltage potentiometer to set the output voltage to the floating charge voltage.5. Connect the battery and conduct a test run.(Steps 1, 2, 3, and 4 are for when the module is connected to the power supply at the input and the output is unloaded without connecting the battery.)LED Constant - Current Driving - Usage Method:1. Determine the operating current and operating voltage of the LED you need to drive.2. Adjust the constant - voltage potentiometer to set the outpvoltage to around 5V.3. Use the 10A current range of a multimeter to measure the output short - circuit current, and simultaneously adjust the constant - current potentiometer to set the output current to the preset LED operating current.4. Adjust the constant - voltage potentiometer to set the output voltage to the LED operating voltage.5. Connect the LED and conduct a test run.(Steps 1, 2, 3, and 4 are for when the module is connected to the power supply at the input and the output is unlo
