This heavy-duty 200W Synchronous Buck Converter is designed for high-efficiency voltage reduction in automotive, solar, and industrial applications. Encased in a rugged aluminum shell, this module offers superior heat dissipation and physical protection compared to standard bare-board converters.

Using synchronous rectification technology, it delivers ultra-high efficiency (up to 94%) with minimal heat generation. It accepts a wide input voltage range (8V–60V) and steps it down to a user-adjustable output (1V–36V). It is capable of handling 10A continuous current (natural cooling) and up to 15A peak current (with added cooling), making it ideal for driving high-power LEDs, charging batteries, or powering 12V/24V devices from 48V telecom or e-bike batteries.

Key Features:

• High Power Density: Supports up to 200W output power (with active cooling) and 15A peak current.

• Wide Input Range: Safely steps down voltages from 8V to 60V DC.

• Synchronous Rectification: Advanced circuit design ensures high efficiency (up to 94%) and low ripple.

• Aluminum Housing: The integrated metal case acts as a heatsink and protects components from dust and accidental shorts.

• Protections: Built-in Over-Current Protection and Reverse Polarity Protection (prevents damage if input +/- are swapped).

• Easy Connections: High-current screw terminals allow for solder-free wiring.

Applications:

• E-Bike/Automotive: Convert 48V/36V battery power to 12V for lights, horns, or audio systems.

• Solar Systems: Efficiently step down solar panel voltage to charge batteries.

• LED Driver: Constant voltage source for high-power LED strips.

• DIY Power Supply: Create a robust adjustable bench power supply.

⚠️ Important Usage Note:

• Potentiometer Adjustment: The small brass screw on the blue component adjusts the voltage. Turn Clockwise to increase voltage, Counter-Clockwise to decrease.

• Heat Management: For loads above 100W or 10A, please add an external cooling fan to prevent overheating.
