LM2596 DC Buck Volt Regulator Converters Constant Voltage & Current 5-36V to 1.25-32V 5A 75W Step Down LED Driver Switching Power Supply with Digital LED Display Voltmeter USB Output Interface

product description Features: Size: 68.2 * 38.8 * 15mm Input voltage: 5-36V Output voltage: 1.25-32V continuously adjustable Output current: adjustable 5A MAX (recommended below 4.5A) Output power: maximum 75W (recommended below 50W in the pressure difference, please reduce the power) Operating temperature: -40 degrees to +85 degrees Working frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: YES Overheat protection: YES (over temperature automatic shutdown output) Enter reverse link protection: NO (add diode if necessary) Installation: 4 3mm screws Connection: terminal or solder terminal, V-IN input, V-OUT output Output: USB female connector, terminal or welding terminal Instructions: 1. Used as over-current protection step-down module. 2. As a variety of voltage battery charger for solar panels, wind turbines and other occasions. 3. For high-power LED constant current driver module. Precautions: 1, if the output power is greater than 3A 35W, please strengthen the heat. 2. If the output voltage can not be adjusted, please potentiometer counterclockwise rotation of more than 10 laps in order to work properly. This is because the factory default output voltage around 17v. 3. If your load is a USB device, make sure the output voltage is 5V. product information Package size 3.5 x 2.4 x 1.2 inches
