DC Buck Converter 5V, Yeeco DC-DC Step Down Voltage Regulator 12V 24V 7-36V to 1.25-32V 12V 5V Volt Reducer Board Board Buck Transformer Power Supply Module with LED Display USB Output & CC CV Mode

Parameters: Input voltage:DC 7-36V Output voltage:DC 1.25-32V (Continuously adjustable) Output current: adjustable, 5A Max(please use it within 4.5A) Output power: 75W Max(please use it within 50W, if the pressure difference is big,please reduce power) Working frequency: 180KHz Conversion efficiency: Up to 96% Working temperature:-40°C - +85°C Installation: 4pcs 3mm screws Module dimensions: L 68.2mm*W 38.8mm* H 15mm description: Short circuit protection : Yes Over temperature : Yes (automatically shut off the output after over temperature) Input reverse polarity protection: No(if necessary, please in input String into high current diode) Wiring: terminal block or solder terminals, V-IN is the input, V-OUT is output Usage: Use as a battery charger Use as high power constant current LED drive module. Use as a normal Step-down modules with over current protection capability. Note: 1. Because the factory default output voltage is 17V. If the module can not be adjusted, the output voltage is always equal to the input voltage.When you encounter this problem, counterclockwise rotation of the potentiometer 10 laps or more, by doing this you can adjust the output voltage. 2.Because of Module output terminal string has a current sampling resistor, it is a normal phenomenon that there will be 0-0.2V voltage drop after connected to the load. 3.When its output is more than 3A/35W, please enhance heat dissipation! 4.This DC converter is single output, the output voltage of the USB port is the same as the output voltage of the module, if your load is USB device, please make sure the module's output voltage is set at 5V. Packing including: 1 x Buck Converter
