300W 10A DC-DC Step-Down Buck Converter Module
Product Description
The 300W 10A DC-DC Step-Down Buck Converter Module is a high-power non-isolated converter designed to reduce higher DC voltages to a lower adjustable output. It supports 6V–40V input and provides an adjustable 1.2V–36V output, making it suitable for power supplies, battery charging, LED driving, solar systems, motor control, and automotive applications.
With conversion efficiency of up to 95% and a large built-in heatsink, the module is designed to provide stable performance under high-current loads.
Adjustable Output
The module allows continuous adjustment of the output voltage from 1.2V to 36V DC, making it suitable for applications requiring different regulated voltage levels.
High-Power Performance
With a maximum output capability of 300W and 10A, the converter can handle demanding DC power applications. For continuous operation near maximum current or power, additional cooling such as a fan is recommended.
Thermal Management
The integrated large heatsink helps dissipate heat generated during voltage conversion, improving stability and reliability during high-load operation.
