Adjustable power supply (12A power is large enough), high power LED driver, LED display driver, lead battery charging, lithium battery charging, car power supply, car laptop power supply (buck), regulated power supply, low voltage system power supply, (such as children Toy car with 12V battery step down to 6V), 24V to 12V 12A \\\\12V to 5V 12A \\\\24V to 5V 12A \24V to 19V20V, etc., a wide range of applications.
1. The fixed lamp current is 0.1 times of the constant current value (used to identify whether the battery is full when charging);
2. A dedicated reference IC and a high-precision sampling resistor are used to make the constant current more stable (50 degrees to 60 degrees constant current 5A when the temperature is less than 5%). Particularly suitable for LED drivers
3. The output current is large, and the maximum output current can reach 12A, which meets most needs.
4.4 high frequency capacitors to effectively reduce output ripple and improve operational stability
5. Double heat sink design, MOS tube Schottky diode independent heat sink, good heat dissipation, mutual influence
6. At the cost, the large-size iron-silicon-aluminum magnetic ring is used to improve the working efficiency, and the pure copper double wire is used to reduce heat and improve efficiency.
7. 3296 multi-turn potentiometer, high voltage and current regulation accuracy, good stability.
8. Dedicated current sampling resistor The current sampling precision is high, the stability is good, and the temperature is small. LED is a must.
9. Two-color indicator light, the working status is clear at a glance. Rechargeable.
10. The voltage and current are all adjustable, and the adjustable power supply is good. The 12A current is large and the power is sufficient.
Battery charging How to use:
1. Determine the float voltage and charge current of the rechargeable battery you need, the input voltage of the module;
2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.
3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;
4. Adjust the constant voltage position device to make the output voltage reach the float voltage;
5. Connect the battery and try to charge.
(1, 2, 3, 4 steps are connected to the power supply of the module, and the output is not connected to the battery.)
LED constant current drive How to use:
1. Determine the operating current and maximum operating voltage at which you need to drive the LEDs;
2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.
3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;
4. Adjust the constant voltage position device to make the output voltage reach the maximum working voltage of the LED;
