Description
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), stabilized power supply, low voltage system power supply, (such as children's Toy car with 12 V battery step down to 6 V), 24 V to 12 V 12A / 12 V to 5 V 12A / 24 V to 5 V 12A / 24 V to 19V20V, etc., a wide range of applications.
Fixed lamp current, which is 0.1 times of constant current value (used to identify whether the battery is full when charging)
The special reference IC and high-precision sampling resistor are used to make the constant current more stable. (The temperature drift is less than 5% when the constant current is 5A from 20 degrees to 60 degrees), which is suitable for LED driving.
The output current is large, and the maximum output current can reach 12A, which meets most needs.
4 high frequency capacitors effectively reduce output ripple and improve operational stability.
Double heat sink design, MOS tube Schottky diode independent heat sink, good heat dissipation, mutual influence.
Use large size iron-silicon-aluminum magnetic ring to improve efficiency, and use pure copper double wire to reduce heat and improve efficiency.
3296 multi-turn potentiometer, high-precision voltage and current regulation, good stability.
Dedicated current sampling resistance, high current sampling accuracy, good stability, small temperature drift, LED essential.
Two-color indicator light, the working status at a glance, and charging is required.
The voltage and current are adjustable, and the adjustable power supply has good effect. The 12A current is large and the power is sufficient.
