Product Overview
This DC-DC buck converter module provides an efficient and adjustable solution for stepping down voltage while supporting both constant voltage (CV) and constant current (CC) operation. With a wide input voltage range from 6V to 40V, the module allows precise adjustment of output voltage and current, delivering up to 300W of power and a maximum current of 20A (15A recommended). Designed for high performance, it features dual 75V/80A MOSFETs, high-frequency low-resistance capacitors for stable output with low ripple, and large 30A screw terminals for secure wiring. The integrated dual heat sinks enhance heat dissipation, ensuring reliable operation in high-power applications.
