5 Pcs LM2596 DC to Buck Converter Voltage Regulator Adjustable Step Down Power Supply Module, 3V-40V Input 1.25V-35V Output, High Q Inductor, 3A Max Current

Package Include: Supplied with 5 pack LM2596 DC to DC buck converter modules, each measuring approximately 44 × 21 mm (including the potentiometer). This set provides multiple step-down power boards for voltage adjustment. Reliable PCB Construction: Each voltage regulator module is manufactured using a durable PCB board for dependable electrical performance and long-term use. Its compact design allows convenient installation in limited spaces, making it suitable for compact electronic assemblies. Simple Voltage Adjustment: Connect the module to a power source, measure the output with a multimeter, then adjust the potentiometer as required. Rotate clockwise to increase the output voltage or anticlockwise to reduce it. The factory setting is approximately 18V, requiring several anticlockwise turns before the voltage begins to decrease. Stable Output Performance: This LM2596 voltage regulator provides an adjustable output voltage with a maximum output current of up to 3A. It operates exclusively as a step-down converter and does not increase voltage. For reliable performance, the input voltage should remain at least 1.5V higher than the required output voltage during operation. Wide Application: Suitable for a wide range of DIY electronics and low-voltage applications. It can be used to supply power for sensors, LED lighting, small motors, controller boards and other electronic circuits, providing flexible voltage regulation for hobbyists, students and repair work.
