About this item
Real-time Monitoring via LED Digital Display The LM-2596 DC to DC step down features a high-precision dual-display LED voltmeter supporting dual voltage readings. It is suitable for step-down conversion applications where the input voltage exceeds the output voltage. Controllers and small DC devices operate by connecting the power supply to the positive and negative terminals (IN+ IN-) of the adjustable step-down module input, and connecting the output device to the positive and negative terminals (OUT+ OUT-) of the step-down module output.
LM-2596 bench power supply module press and hold the switch button for over 4 seconds to enter input voltage calibration (4-40V). After adjusting the calibration value, press and hold the switch button for over 2 seconds to enter output voltage calibration (1.25–37V). Calibration values are permanently stored, eliminating measurement errors and adapting to various precision equipment power supply scenarios.
Easy to operate and hassle-free Features touch buttons that allow you to switch between voltmeter display modes with a single touch (IN/OUT indicator light on), and automatically retain the last settings after power is turned off. Press and hold for 1 second to turn off the voltmeter (energy saving), and press briefly to start the display. Dual wiring methods: Equipped with wiring terminals (no soldering required) and solder pads, allowing both novice and professional users to quickly install.
Multiple safety protections The converter's input terminal is equipped with a built-in diode to prevent damage to the device caused by reverse connection, ensuring your safety. It also features a dual protection mechanism to prevent overheating and short circuits. The operating current can reach approximately 2A (maximum 3A). Please ensure sufficient space for heat dissipation. For loads exceeding 15W, it is recommended to add heat dissipation measures to ensure safe system operation. Please use a multimeter to check the voltage when powering on for the first time!
High-efficiency voltage reduction The Board is second-generation LM-2596S chip (150KHz) is extremely flexible and suitable for automotive power supplies, DIY projects, bench testing, small DC loads, or industrial equipment. Whether you are a professional or a beginner, this converter is the ideal choice for you.
