DC CC 9A 300W Step Down Buck Converter 5-40V To 1.2-35V Power module (adjustable voltage and current)
– 100% brand new and high quality
– Use a dedicated benchmark IC, and high-precision current sensing resistor, can make more stable constant current
– High output current, the max output current can reach 9A.
– Low output ripple , high frequency capacitor reduces output ripple.
– Suitable for LED driver.
– High-power LED constant current driver ,
– Lithium battery(or Iron battery) charge,
– 6V, 12V, 14V, 24V battery charge ,
– Nickel -cadmium nickel-metal hydride battery ( battery pack ) charge ,
– Solar panels and wind turbines
1- Make sure of the battery float voltage and charging current that you need, the input voltage of the module.
2- Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3- 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.
4- Adjust the constant voltage potentiometer make the output voltage reaches the float voltage;
5- Connected to the battery, try to charge.
6- (1,2,3,4 steps to connect the power module input,output no-load does not connect battery.)
