Description:
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.)
Specifications:
Color: Picture Color
Size: 65* 47* 23.5mm
Package Included:
1 * DC-DC Adjustable Constant Voltage Constant Module
typical application:
Adjustable power supply (12A power enough), high-power LED drive, LED display drive, lead-acid battery charging, lithium battery charging, car power supply, car laptop 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 12A \\12V to 5V 12A \\24V to 5V 12A \\24V to 19V20V, etc., the application range is very wide.
1. The fixed lamp current is 0.1 times the constant current value (used to identify whether the battery is full when charging),
2. A dedicated 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). Especially suitable for LED driver
3. The output current is large, and the maximum output current can reach 12A, which meets most needs.
4.4 high-frequency capacitors, effectively reducing output ripple and improving working stability
5. Double heat sink design, independent heat sink for MOS tube Schottky diode, good heat dissipation, no mutual influence
6. Use large-size iron-silicon-aluminum magnetic ring at any cost to improve work efficiency, and use pure copper double wires to reduce heat generation and improve efficiency.
7. 3296 multi-turn potentiometer, with high voltage and current adjustment accuracy and good stability.
8. Special current sampling resistor High current sampling accuracy, good stability, low temperature drift. Required for LED.
9. Two-color indicator light, the working status is clear at a glance. Required for charging.
10. Both voltage and current can be adjusted. It is effective as an adjustable power supply. The 12A current is large and the power is sufficient.
