Battery charging method:

1 determine the float voltage you need to charge the battery and charging current, input voltage module;

2 adjustable constant potentiometer, the output voltage is regulated to 5V.

3 multimeter 10A current block measurement output short circuit current, and adjusting the constant current charging current potentiometer output current reaches a predetermined value;

4 adjustable constant potentiometer to the output voltage to the floating charge voltage;

5 battery charging, test.

(1, 2, 3, 4 steps for the module input power, output no-load not connected with the battery. )



LED constant current driving method:

1 to determine the current you need to drive LED and maximum working voltage;

2 adjustable constant potentiometer, the output voltage is regulated to 5V.

3 multimeter 10A current block measurement output short circuit current, while regulating constant current potentiometer output current up to LED working current of a predetermined;

4 adjustable constant potentiometer to the output voltage to the LED maximum working voltage;

5 connected to the LED, the test machine.

(1, 2, 3, 4 steps for the module input power, output no-load not connected with the LED lamps. )
