DC Step Down Module 16-120VDC to 12VDC 3A

This module uses buck (step-down) conversion technology, which efficiently reduces voltage while maintaining stable output and minimizing energy loss. It supports a very wide input voltage range (16V to 120V DC), making it highly versatile for various systems including electric vehicles, solar setups, and automation systems.

Despite the wide input range, the output remains fixed at 12V, ensuring compatibility with common electronics such as LED lights, routers, cameras, and control circuits. It can deliver up to 3A continuous current (36W), making it suitable for moderate power loads.

The module also includes built-in protection features like overcurrent, overvoltage, and short-circuit protection, ensuring safe and reliable operation even in demanding environments.
