Features:
Indicator light current is 0.1 times of the current which is used to identify whether it is fully charged.
Made from special IC and high accuracy sampling resistors which
ensures a more stable constant current, specially fit LED driver.
Four high frequency capacitors can reduce output ripple and good for stability.
Two independent heat sink design are better for heat dissipation.
The inductor of large sendust core and double copper wiring would improve efficiency and decrease heat.
Widely used for high power LED drive, lithium or acid battery, low
voltage system power supply, 6V, 12V, 14V, 24V battery charging and
regulated power supply.
When power tube temperature is over 65
celsius
, please add cooling fan to enhance heat dissipation.

Instruction:
Battery Charge:
1. Make sure of the battery float voltage and charging current that you need, as well as the input voltage of the module.
2. Adjust the constant voltage potentiometer and adjust the output voltage to about 5V.
3.Use the multimeter in 8A current scale to measure output short circuit current, and adjust the
current potentiometer to make the output current to the expected charging current value.
4. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage.
5. Connected to the battery, try to charge.
(1,2,3,4 steps to connect the power module input,output no load does not connect battery.)
LED Constant Current Drive:
1. Make sure the operating current and Maximum operating Voltage of the LED you need to drive.
2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3. Use the multimeter in 8A 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. Adjust the constant voltage potentiometer to make the output voltage reach the maximum LED operating voltage.
5. Connect LED, test.
(1,2,3,4 steps to connect the power module input, output No load does not connect LED.)
