    • Load Regulation: ± 1%

    • Voltage Regulation: ± 0.5%

    • Current Accuracy and temperature: Actual Testing, Temperature changes from 20 degrees To 100 degrees, Constant current value change Less than 1% (constant current value 1A)

    • Dynamic response speed: 5% 200uS

    • Potentiometer adjustment direction:Clockwise (increase),Counterclockwise (decrease)

    • Indicator LED: Charging LED Red, Full Charge LED Green

    • Output Short-circuit Protection:YES

    • Input Reverse Polarity Protection:YES

    • Output Prevent Countercurrent: YES

    Battery Charging Method:

    • Make sure the recharge battery float voltage and charge current, input voltage of the module.

    • adjust constant voltage regulator, the output voltage about 3V.

    • With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current gets a predetermined charge current value;

    • Adjust Constant regulator allows Output voltage gets the float voltage;

    • connected to the battery, try charging. (1,2,3,4 step input connect power, output do not connect battery.)

    LED Constant Current Driver Usage:

    • Make sure LED current and the maximum operating voltage;

    • adjust constant voltage regulator, the output voltage about 3V.

    • With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current gets a predetermined LED working current value;

    • Adjust Constant regulator allows Output voltage get LED maximum working voltage;

    • Connected to the LED, test (1,2,3,4 take steps input connect power, output do not connected LED.)

    Applications:

    • Battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind generators.

    • Solar Panel, Wind generator voltage regulator, Car Power Supply.
