Adjustable output voltage from DC 3 V to 40 V, allowing compatibility with a wide range of devices and configurations for versatile use. conversion efficiency up to 95%, delivering a stable power supply with reduced heat and improved reliability. Wide input voltage range from DC 5 V to 60 V, enabling use with multiple sources and installations without changing modules. Enhanced heat dissipation, designed to handle up to 5 A of output current with improved cooling when the load exceeds 2 A. Use scenarios: Prototyping and electronics development: power microcontrollers, sensors, and test circuits from a higher voltage source by setting the precise output voltage needed. LED lighting and drivers: provide stable voltage for LED strips or driver circuits up to 40 V and up to 5 A. Automotive, solar, and bench power setups: convert higher voltage sources to safe, regulated levels for various devices in automotive, solar, or lab environments.
