Battery use:
-
l Make sure of the voltage and current of the battery you need to charge
-
l Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
-
l Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
-
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
-
l The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
-
l Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries)
LED Constant Current Driver Use:
-
l Make sure operating current and Max operating Voltage of the LED you need to drive
-
l Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage
-
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer
-
l to make sure the output current to the expected LED operating current
-
l Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)
