About the item

  • Input voltage: 7-40V Output voltage: 1.2-35V (continuously adjustable) Output Current: 8A (power tube temperature exceeds 65°C please add cooling fan) Output Power: Maximum power is about 300W (power tube temperature exceeds 65°C please add cooling fan) Size: Approx. 2.55*1.88*0.94inch / 6.5*4.8*2.4cm(Length*width*thickness)..
  • Non-isolated step-down constant current, constant voltage module (CC CV) charging module.
  • Output Power: Maximum power is about 300W.
  • Potentiometer adjustment direction: clockwise (increase) , counterclockwise (decrease), the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC).
  • No-load current: Typical 20mA (24V switch 12V) Load regulation: ± 1% ( constant ) Voltage regulation: ± 1%.
Applications: 1. High-power LED driver. 2. Lithium battery(or lead accumulator) charge. 3. Vehicle-ed power supply. 4. Low voltage system power supply. 5. 6V, 12V, 14V, 24V battery charge. 6. On-board laptop power supply. 7. regulated power supply. 8.Low voltage power supply system. Battery charge: 1. Make sure of the battery float voltage and charging current that you need, as well as the input voltage of the module. 2. Adjust the constant voltage potentiometer and 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 the output current to the expected charging current value. 4. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage. 5. Connected to the battery, try to charge. (1,2,3,4 steps to connect the power module input,output no-load does not connect battery.) LED constant current drive: 1. Make sure the operating current and Max operating Voltage of the LED you need to drive. 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 LED operating current. 4. Adjust the constant voltage potentiometer to make the output voltage reach the maximum LED operating voltage. 5. Connect LED, test. (1,2,3,4 steps to connect the power module input, output No-load does not connect LED.)
