Precise LED Voltage Monitoring: Equipped with a clear LED numeric display featuring ±0.1V measurement accuracy. Supports 4–40V input and 1.25–37V output ranges. The voltmeter automatically turns off when input voltage falls below 4V and can be manually disabled/reactivated via a tactile switch (hold 1–4s to disable, short press to enable)
High-Efficiency LM2596 Regulation Core: Utilizes a second-generation LM2596 buck converter operating at 150kHz switching frequency for optimized efficiency and low heat generation. Built with solid capacitors for enhanced stability, reduced ripple, and reliable filtering of high-frequency noise
User-Friendly Adjustment and Connectivity: Output voltage can be easily adjusted using a miniature screwdriver. Designed with solder-free terminal blocks for simplified wiring, making it accessible for both beginners and professionals
Integrated Safety and Protection: Includes reverse-polarity protection diodes on the input side, alongside over-temperature and short-circuit safeguards. For sustained high-power operation (above 15W), additional heat dissipation is recommended to ensure optimal performance
Versatile Application Scenarios: Ideal for diverse uses such as automotive power adaptation, DIY electronics, industrial control systems, and laboratory power supplies. Combines professional-grade performance with straightforward operation
