Description
The XH-M401 DC-DC Buck Converter Module (B-Series) is a high-efficiency, high-power step-down voltage regulator designed for demanding power management tasks. Built around the robust XL4016E1 switching regulator chip, this module is engineered to convert a higher DC input voltage into a lower, stable DC output with up to 94% efficiency.
This “B-Series” variant is optimized for reliability in DIY power supplies, battery-operated systems, and industrial control cabinets. It features an integrated large-area heatsink and a high-precision potentiometer with a built-in “click” power switch, allowing users to adjust voltage and power the unit on or off using a single intuitive control knob.
Key Features
- High Power Output: Capable of delivering a continuous 5A current, with a peak capacity of 8A (short-term) for high-draw applications.
- Integrated Power Switch: The voltage adjustment potentiometer includes a built-in switch; turning the knob fully counter-clockwise turns off the module completely.
- Efficient Heat Dissipation: Features a specialized dual-aluminum heatsink design to maintain stable operating temperatures during high-load tasks.
- Advanced Protection Suite: Includes built-in over-temperature protection, over-current protection, and short-circuit protection to safeguard both the module and connected electronics.
- Stable Regulation: Utilizes high-frequency switching technology (180kHz) to ensure low-ripple output and consistent voltage stability.
- Premium Componentry: Uses high-quality inductors and solid-state capacitors for long-term durability in industrial environments.
