Overview
The XH-M407 is a high-power DC-DC step-down module that utilizes the XL4016E1 switching regulator chip. It is engineered to bridge the gap between hobbyist modules and industrial power supplies. The standout feature is the integrated 3-digit LED Voltmeter, which allows you to monitor your output voltage without needing a multimeter. With its massive dual heatsinks and high-quality inductor, it can output up to 200W of power, making it the perfect choice for demanding robotics and CNC projects.
Key Features
High Current Delivery: Supports up to 8A peak current (5A continuous), far exceeding the 3A limit of standard buck converters.
Built-in Voltmeter: Real-time digital display of output voltage for easy calibration and monitoring.
Exceptional Efficiency: Up to 94% conversion efficiency, meaning less energy is wasted as heat.
Superior Cooling: Equipped with large aluminum heatsinks to ensure stable operation under heavy loads.
Safe Design: Includes over-current, over-temperature, and short-circuit protection.
