    Product Details

    Non-isolated step-down (CC CV) charging module IN:7-35V


    Applications:

    • High-power LED constant current driver,lithium battery charger (including ferroelectric)
    • 4V, 6V, 12V, 14V, 24V battery charger,Nickel cadmium,nickel metal hydride batteries charger,
    • solar panels and wind turbines.

    Features:

    • Non-isolated step-down constant current, constant voltage module (CC CV) charging module
    • Input voltage: 7-35V
    • Output voltage: continuously adjustable (1.25-30V)
    • Minimum Voltage difference: 2V
    • Output current: rated 3A, the largest 4A (more than 15W, please install the heat sink)
    • Constant current range :0-4A (adjustable)
    • Size: ultra-small size 49 (L) * 23.4 (W) * 11.4 (H) mm (without potentiometer)
    • Output power: natural cooling 15W, 25W with heatsink
    • Conversion efficiency: up to 92% (output voltage higher, higher the efficiency)
    • Output ripple: 20M bandwidth (for reference only)
    • Input 12V Output 5V 3A 60mV (MAX)
    • Operating temperature: Industrial grade (-40 ℃ to +85 ℃) 
    • (ambient temperature exceeds 40 degrees, lower power use, or add one heatsink)
    • Full load temperature rise: 45 °C
    • No-load Current: Typical 10mA (12V switch to 4.2V)
    • Load regulation: ± 1%
    • Voltage regulation: ± 0.5%
    • Dynamic response speed: 5% 200uS
    • Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
    • Indicator: Red LED constant current, the charge in light red, light blue, fully charged
    • Output short circuit protection: Yes, constant current (constant current value of the current settings)
    • Input reverse polarity protection: No, please comply with our plate or in the input reverse polarity protection diode in series.
    • Connection mode: welded, plus pin can be directly soldered on the PCB to matching pin, radiator, shell.

    For Battery charge use:

    • 1) Make sure of the voltage and current of the battery you need to charge.
    • 2) Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
    • 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) Charge transfer lamp current default value is 0.1 times of the charging current(constant current value), For lamp current adjustment, please turn potentiometer adjustment;
    • 5)Connected to the battery, try charging.
      (1,2,3,4 steps to connect the power module input and output load does not take batteries.)

    For LED constant current driver usage:

    • 1)Make sure operating current and Max operating Voltage of the LED you need to drive.
    • 2)Adjust the constant voltage potentiometer to make sure the out put Voltage is up to LED Max operating Voltage.
    • 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)Join LED,test.
      (1,2,3,4 steps to connect the power module input and output load does not take LED.)

    Note: The item do not include the heatsink,  you need buy the heatsink seperately.
