DCDC stepdown converter module with wide 6–40 V input and precise adjustable output voltage and current. Key benefits Wide input range (6–40 V) compatible with common 12 V and 24 V vehicle, battery and solar systems — simplifies integration across different power sources. conversion efficiency reduces heat and power loss — up to 96% efficiency (measured at 20 A when converting 24 V to 12 V). Robust current switching: equipped with a 75 V / 80 A dual MOS tube for reliable performance in demanding loads. Improved thermal management: bilateral heat sinks, 25 mm height, help dissipate heat under sustained load. Stable, lowripple output: input and output use frequency, lowimpedance electrolytic capacitors to minimize voltage ripple and maintain steady power delivery. Precise control: stepdown converter allows accurate adjustment of both output voltage and current to match device or battery requirements. Important specifications and attributes Function: buck (stepdown) DCDC converter with adjustable output voltage and current. Input voltage: 6 V to 40 V. Efficiency: up to 96% (measurement condition: 24 V to 12 V conversion at 20 A). Power switching: dual MOS tube rated 75 V / 80 A. Thermal design: bilateral heat sinks, 25 mm height. Filtering: frequency, lowimpedance electrolytic capacitors on input and output for low ripple and stable output. Typical applications Automotive and mobile power: step down 24 V alternator systems or variable battery voltages to stable 12 V for accessories, audio equipment, or charging circuits. Renewable and battery systems: convert highervoltage battery banks or solar arrays to regulated lowervoltage supplies for chargers, controllers, or 12 V loads. Industrial and electronics projects: supply stable, lowripple power for motors, LED arrays, control electronics, and testing benches where precise voltage/current control and thermal reliability are needed. Why choose this module Delivers efficient, stable DC power across a broad input range while providing precise voltage and current control. Built with current MOSFETs, quality electrolytic capacitors, and dedicated heat sinks to support practical, sustained use without excessive ripple or thermal stress. Installation notes Verify input voltage is within 6–40 V before connecting. Use appropriate wiring and fusing according to the application and expected current. Allow airflow around the bilateral 25 mm heat sinks to maximize thermal performance.
