120W DC-DC Converter (15-40V Input, 12V 10A Output)

The 120W DC-DC Converter is a rugged step-down power module that transforms a wide 15–40V DC input into a stable 12V DC output at up to 10A. With 90% conversion efficiency and a sealed protective housing, it is ideal for makers, robotics builders, and engineers powering high-load electronics in demanding environments.

High-power 12V voltage regulation

This step-down converter transforms a 15–40V DC input into a regulated 12V DC supply capable of delivering up to 10A. Achieving up to 90% conversion efficiency, the unit minimises energy loss and limits thermal buildup during operation.

Sealed waterproof and shockproof casing

A fully enclosed waterproof and shock-resistant case protects internal components from moisture, dust, and mechanical vibration. Measuring 74 x 74 x 32 mm and weighing 0.28 kg, the module operates reliably at temperatures up to 80 ℃.

Comprehensive electrical safety protection

The converter integrates overvoltage, overcurrent, overheat, and short-circuit protection circuits. These multi-layered safeguards automatically respond to abnormal operating conditions to protect downstream electronics.

Versatile robotics and automation deployment

With its 120W output capacity, this converter serves as a dependable power source for embedded PC systems, mobile robotics platforms, and automotive electronics. It is equally suited for outdoor monitoring equipment and field-deployed industrial automation hardware.
