หากคุณมีคำถามใด ๆ หรือต้องการที่จะให้ข้อมูลโปรดปรึกษาแบรนด์: SUNLEPHANT Tips: (Spot: The maximum current is 8-9A, the maximum input voltage is 40V, and the output voltage is up to 35V) (Because the 12A current chip manufacturer stopped production, the replacement chip current was reduced from the previous 12A to 8A current (the actual test maximum current is around 9A), the input voltage was increased from the previous 32V to 40V, and the output voltage was increased from the previous 28V to 35V. Powering 10 strings of high-power LEDs. 12A chips will be notified when they arrive.) QS-2405CCBD-12A power module Dimensions: 65 (length) * 47 (width) * 23.5 (height) mm typical application: 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 (the temperature drift is less than 5% at a constant current of 5 degrees from 20 degrees to 60 degrees). 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. Module parameter Module nature: non-isolated buck constant current, constant voltage module (CC CV) charging module Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-hydrogen battery (battery pack) charging, solar panels, wind turbines Input voltage: 7-32V (without constant current 5-32V) Output voltage: (1) continuously adjustable (0.8-28V)          (2) Fixed out
