DC-DC step-down adjustable constant voltage current high power 10A solar charging LED drive car module | Обустройство дома

Output voltage: continuously adjustable (0.8-28V)Input voltage: 7-32VConversion efficiency: 95%Switching frequency: 180KHZOther power: short circuit protectionConstant current range: 0.2-10A (adjustable)Minimum pressure difference: 1VModule nature: non-synchronous rectification isolation buck constant current constant voltage module CC CV charging moduleProduct size: 65*47*23.5 (L**H)application:Adjustable power supply (10A power is large enough), high-power LED driver, LED display drive lead battery charging, lithium battery charging, car power supply, car notebook power supply (buck) regulated power supply, low-voltage system power supply, (such as children’s toys 12V battery step down to 6V), 24V to 12V12A 24V to 5V 10A 24V to 19V 20V, etc.How to charge the battery:1. The float voltage and charging current of the rechargeable battery you need to reach the input voltage of the module2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V,3. Use a multimeter 10A current block to measure the output short-circuit current4. Connect the battery and try charging.Module parameters:Module nature: non-isolated buck constant current, constant voltage module (CC CV) charging moduleScope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric) 4V, 6V12V, 24V battery charging, Nifu NiMH battery (battery pack) charging, solar panel, wind generator. Input voltage: 7-32V (without constant current 5-32V)Output current: two big 10A (please add a fan to dissipate the temperature when the power port temperature exceeds 65 degrees, generally no fan is required in an open environment within 24V to 12V 6A)Constant current range: 0.2-10A (adjustable) (no such function without constant current)Minimum pressure difference: 1VOutput power: 3 large power about 300W, power tube temperature exceeds 65 degrees, please add fan conversion efficiency: second high about 95% (the higher the output voltage, the higher the efficiency)How to use LED constant current drive:1. Determine the working current and maximum working voltage of the LED you need to drive;2. Adjust the constant voltage potentiometer to adjust the programmed voltage to about 5V.3. Use a multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to use the car output current to reach the predetermined LED working current.4. Adjust the constant voltage potentiometer to make the output voltage to LED. Y high engineering 2 as the voltage5. Connect the LED and test the machine(The steps of 1.2.3.4 are that the module input is connected to the power supply, and the output is no-load without connecting the LED lamp)
