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.
