300W 10A DC-DC Step-down Buck Converter Adjustable Constant Voltage Module

The 300W 10A DC-DC Step-down Buck Converter Module is a powerful and efficient solution for converting higher DC input voltages (6V–40V) into a lower, precise output voltage (1.2V–36V). Designed for high-performance applications, this non-isolated step-down module utilizes a high-frequency switching regulator to achieve an impressive conversion efficiency of up to 95%.

Equipped with a large, built-in heatsink, the module offers superior thermal management, ensuring stability and safety even under high-current loads up to 10A. It is an ideal component for building DIY adjustable power supplies, regulating solar panel output, controlling DC motor speed, or driving high-power LED lights.

Disclaimer This module is intended for use by individuals with basic knowledge of electronics. Please ensure correct input/output polarity before connecting power, as reverse polarity may damage the module. For continuous high-load operation (near 300W or 10A), additional cooling (such as a fan) may be required to prevent overheating. Do not exceed the maximum input voltage of 40V.
