1. Fixed turn lamp current is 0.1 times the current value
( Used to identify whether the battery is fully charged When charging).
2. Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%).Particularly suitable for LED driver.
3. High output current, the max output current can reach 8A.
4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
5. Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good, and won't affect each other.
6. Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
7. 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
8. Double color lamp, working condition be clear at a glance
9. Voltage and current are adjustable,wich effect is good.

Applications:
Adjustable power supply (9A power is large enough), high-power LED driver, LED display driver, lead battery charging, lithium battery charging, vehicle power supply, vehicle notebook power supply (buck), regulated power supply, low-voltage system power supply, (such as children The toy car uses 12V battery to step down to 6V), 24V to 12V 9A, 12V to 5V 9A, 24V to 5V 9A, 24V to 19V, 20V, etc., so it has a wide application.

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 10A 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.

Applications:
1) DIY an output adjustable car power supply, you only need to connect your 12V power supply to the input, you can freely and continuously adjust the output voltage (14-35V), but the output voltage cannot be lower than the input voltage. 2) Car notebook power supply. The input is connected to your 12V power supply, and the output is adjusted to the voltage of your notebook to work.
3) Boost charger, you can use 12V power supply to charge batteries higher than 12V, such as 24V batteries. 4) To supply power to your electronic equipment, as long as the voltage is adjusted to the voltage you need and the current does not exceed the rated current, it can work normally. 5) The power supply of the front stage of the system, when you are working on a project and the input is 10-18V, and your system board needs about 24V power supply and its power is very large, the power of ordinary DC-DC modules is too small , choose our module, you can work directly on the machine without debugging, and easily achieve high-efficiency and high-power boost.
