HW-920 DC-DC Buck Converter Adjustable Step-Down Power Supply Module 10A | High Efficiency Voltage Regulator | Sri Lanka

The HW-920 DC-DC Buck Converter is a high-performance adjustable step-down power supply module designed for efficient voltage regulation in a wide range of electronic applications. This module converts a higher DC input voltage into a stable, lower adjustable output voltage, making it ideal for powering sensitive devices. Built with a durable heatsink and high-quality components, the HW-920 ensures reliable performance even under heavy load conditions.

This module supports a wide input voltage range (typically 8V–60V DC) and delivers a high output current of up to 10A with proper cooling. It features dual potentiometers (W103 & W104) for precise voltage and current adjustment, allowing users to fine-tune output according to project requirements. The onboard inductor, high-speed switching IC, and low ESR capacitors provide high efficiency (up to 95%) and minimal ripple output. The large aluminum heatsink ensures effective thermal management, making it suitable for continuous operation.

Technically, the HW-920 uses a switching regulator topology (buck converter) to step down voltage efficiently compared to linear regulators. It includes protection features such as overcurrent and thermal protection, enhancing safety and durability. The screw terminals allow secure and easy connection for both input and output.

This module is widely used in battery charging systems, solar power projects, LED drivers, motor control circuits, DIY electronics, and embedded systems. Whether you are a hobbyist or a professional, the HW-920 offers flexibility and power in one compact unit.
