Battery Charging Method
1. Make sure the recharge battery float voltage and charge current, input voltage of the module.
2. adjust constant voltage regulator, the output voltage about 3V.
3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current gets a predetermined charge current value;
4. Adjust Constant regulator allows Output voltage gets the float voltage;
5. connected to the battery, try charging.
(1,2,3,4 step input connect power, output do not connect battery.)
LED Constant Current Driver Usage
1. Make sure LED current and the maximum operating voltage;
2. adjust constant voltage regulator, the output voltage about 3V.
3. 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;
4. Adjust Constant regulator allows Output voltage get LED maximum working voltage;
5. Connected to the LED, test.
(1,2,3,4 take steps input connect power, output do not connected LED.)
