Description

    • Module Properties: non-isolated step-down constant current, constant voltage module (the CC the CV ) charging module
    • Scope: Large power LED constant current driver, lithium battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind turbines
    • Input voltage: 7 -35 V If you need a higher voltage, please contact me directly
    • Output voltage:(1) continuously adjustable ( 1.25 of -30V was )( 2 ) fixed output (1.25 -30V choose between) , purchase please tell treasurer. (Temporarily only for volume customers, all the hair samples adjustable)(3) If you need a higher voltage, please contact me directly
    • Output Current: maximum 3A (more than 15W, please install heat sink )
    • Constant current range: 0-3A (adjustable)
    • Turn lamp current: constant current value * (1% -100%), turn the lamp current constant current value linkage , such as a constant current value of 3A, turn the lamp current is set to a constant current of 0.1 times (0.1 * 3A = 0.3A) , when adjusted constant current value to 2A when, this time turn the lamp current constant current of 0.1 times (0.1 * 2A = 0.2A).
    • Default shipping has been adjusted to 0.1 times
    • Minimum pressure: 2V
    • Output power: natural cooling 15W, plus heat sink 25 the W
    • Conversion efficiency: 92% (up to 92% (the higher the output voltage, the 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 to enhance heat dissipation)
    • Full load temperature rise: 45 deg.℃
    • No-load current: Typical 10mA (12V switch 4.2V)
    • Load regulation: ± 1 %
    • Voltage regulation: ± 0.5%
    • Dynamic response speed: 5% 200uS Potentiometer adjustment
    • direction: clockwise (increase), counterclockwise (decrease)
    • Indicator: constant current Indicator Red, Charging indicator light red, blue LED charging is completed
    • Output short circuit protection: Yes, constant current (constant current setting values)
    • Input reverse polarity protection: None, please with our reverse polarity protection board or enter a series diodes.
    • Connection: After welding, plus pin can be directly soldered to the PCB An optional pin, radiator, shell.

    Battery charging methods:

    1. Determine the float voltage and charging current that you need to charge battery and module’s input voltage.
    2. Adjustable constant potentiometer, the output voltage is regulated to about 3V.
    3. Use multimeter 10A current block measurement output short circuit current, meanwhile adjusting the constant current potentiometer to make output current reaches predetermined current value.
    4. The charging turn lamp current default is 0.1 times of charging current (current value ).If you need, adjust turn lamp current potentiometer please (generally do not adjust).
    5. Adjustable constant potentiometer to make the output voltage to the floating charge voltage.
    6. Connect battery, to try charging (1, 2, 3, 4, 5 steps is the module input power, output no-load not connected to the battery).

    LED constant current driving use methods:

    1. Determine you need to drive LED operate current and maximum working voltage.
    2. regulation constant potentiometer; 2, the output voltage is regulated to 3V.
    3. Use multimeter 10A current block measurement output short circuit current, meanwhile adjusting the constant current potentiometer to make output current reaches LED operating current.
    4. Adjustable constant potentiometer to make the output voltage to the LED maximum working voltage.
    5. Connected to the LED, try test machine. (1, 2, 3, 4 steps is the module input power, output no-load not connected to the LED lamps).
