1PCS/3PCS LM2596 DC buck power module 3A Adjustable buck module LM2596 Voltage regulator 24V 12V 5V 3V

Wiring: IN+ positive input negative OUT input + positive output negative output 1. Input voltage range: DC 3.2V to 40V (input voltage must be more than 1.5V higher than output voltage. 2. Output voltage range: DC 1.25V to 35V continuously adjustable voltage, high efficiency (up to 92%) output current maximum 3A module use Method: 1. Turn on the power supply (3-40V), the power indicator light is on, and the module is working normally. 2. Adjust the blue potentiometer knob (generally rotate clockwise to increase, counterclockwise to decrease) and monitor the output voltage with a multimeter until it reaches The required voltage. Note: 1. It is recommended to use 2.5A current for long-term work, and add a heat sink (output more than 10W); because it is a step-down module, in order to ensure stable output, please ensure that the voltage drop of 1.5V is small. Application: 1 , car control power supply, just connect the input end of this module to the car ignition. For the power supply, the potentiometer can be adjusted, the output voltage can be adjusted from 1.25-30V, and it can charge mobile phones, MP3, MP4, PSP, etc. Many powerful devices, Very simple and easy. 2. The power supply of electronic equipment. When the equipment needs 3-35V power supply and the power supply of the corresponding voltage at hand, this module can easily adjust the voltage to the required voltage to solve this problem. 3. System working voltage Test, you can use this module to debug the working voltage range of various voltage test systems when doing projects, which is very simple and convenient.
