Elecbee 3A Multi-Channel Step-Down Buck Converter Module, Adjustable 2V-28V & Fixed 3.3V/5V/12V DC Voltage Regulator Board, 50W Power Supply

The Elecbee Multi-Channel Buck Converter is the ultimate solution for engineers and hobbyists struggling with mismatched voltage requirements in complex projects. Instead of cluttering your workspace with multiple power bricks, this single board transforms a wide-range DC input into four distinct, stable outputs. It effectively solves voltage instability and power distribution issues for microcontrollers, sensors, and actuators, ensuring your sensitive electronics receive clean, regulated power every time.

This high-efficiency DC-DC step-down module is built for performance and reliability. It manages a total power output of 50W across four channels, with each channel capable of handling 3A of current. The technical specifications include:

• Fixed Outputs: 3.3V (±3%), 5V (±3%), and 12V (±3%)
• Adjustable Output: 2V to 28V via precision potentiometer
• Input Range: 4.5V to 30V DC
• Dimensions: 88 x 55 x 15mm (Ultra-slim profile)

Designed for industrial-grade safety, the board features robust reverse connection protection to prevent burnout from accidental wiring errors. The onboard thermal management and over-current safeguards ensure the module operates safely even during peak loads. Weighing only 57g, this lightweight yet powerful voltage regulator board is a plug-and-play component suitable for robotics, telecom equipment, and multi-rail breadboard testing.
