  Description:


For Battery charge use:

  • 1) Make sure of the voltage and current of the battery you need to charge.
  • 2) Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
  • 3) 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.
  • 4) Charge transfer lamp current default value is 0.1 times of the charging current(constant current value), For lamp current adjustment, please turn potentiometer adjustment;
  • 5)Connected to the battery, try charging.
    (1,2,3,4 steps to connect the power module input and output load does not take batteries.)

For LED constant current driver usage:

  • 1)Make sure operating current and Max operating Voltage of the LED you need to drive.
  • 2)Adjust the constant voltage potentiometer to make sure the out put Voltage is up to LED Max operating Voltage.
  • 3)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 LED operating current.
  • 4)Join LED,test.
    (1,2,3,4 steps to connect the power module input and output load does not take LED.)
