- Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
- 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
- The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
- 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:
- Make sure operating current and Max operating Voltage of the LED you need to drive
- 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
- Make sure the output current to the expected LED operating current
- Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)This module's power output is affect by the module itself-capacity and pre-and post-class load and other factors; the following data for professional equipment measured results, without considering other factors.
