DC Max 5A Step Down Buck Converter 5-32V to 1.2-31V Solar Charger Constant Voltage Adjustable Power Supply Module LED Driver

DC Max 5A Step Down Buck Converter 5-32V to 1.2-31V Solar Charger Constant Voltage Adjustable Power Supply Module LED Driver Descrtion: 1: Wide range of applications 2: With turn lights 3: Small size 4: With overcurrent protection 5: Short circuit protection Parameters: Input voltage: DC 5-32V Output voltage: DC 1.2-31V Output current: rated 3A 5A MAX Output power: Rated 36W MAX: 60W The output power is related to the input voltage value, The lower the input voltage, the smaller the output power (over the rated recommended air cooling) Conversion efficiency: 88%-94% related to input and output voltage and current Overcurrent protection: Yes (overcurrent protection value is output constant current setting value) Short circuit protection: yes (set value for output constant current) Working frequency: 180KHz Module size: 49* 23* 16mm Application range: 1. DIY a regulated power supply with constant current function, not afraid of short circuit during use, which can protect the load. 2. Power your electronic devices. 3. Charge all kinds of batteries, set the charging voltage and charging current according to the batteries of different voltages and capacities, with a charging indication function, which is convenient to observe the charging status. 4. Use solar panel power supply to charge various batteries, with constant current function, which can prevent the battery from overcharging and effectively protect the battery. 5. Drive high-power LEDs, which can be freely combined in series and parallel, 6. As a car power supply, power supply for your mobile phone or various digital products. Note: This module uses negative sampling current, the input negative and output negative cannot be connected together, otherwise the constant current function will fail. 1. Set the output voltage: Set the output voltage to the required voltage according to the float voltage value of the battery you want to charge, or the voltage value of the LED after series or parallel connection, and adjust the output voltage potentiometer (CV). (without load) 2. Set the output constant current value: After setting the output voltage, adjust the CC potentiometer counterclockwise about 20 turns, short-circuit the output with the 20A current gear of the multimeter, and adjust the CC potentiometer to the current value you need. Note: When setting constant current, the voltage should be higher than 0.8V, otherwise the constant current function will fail. The output of the module is equped with an anti-backflow diode, and the output can be directly connected to the battery. Package List: 1 x DC buck module
