BEC12S-PRO – 9-55V to 5V/8V/12V 5A Step-Down Regulator

The Mateksys BEC12S-PRO is a high-efficiency step-down (buck) voltage regulator designed for drones, RC electronics, and other power-sensitive applications. With a wide input voltage range of 9V to 55V, this power module offers three selectable output options: 5.2V (default), 8V, and 12V, making it highly versatile for different setups.

This regulator provides continuous 5A output current with a peak capacity of 9A, ensuring stable power delivery to sensitive components. With an efficiency rating of 88% to 96%, it minimizes heat generation and power loss. The TVS protection, thermal shutdown, overcurrent protection, and short-circuit tolerance enhance safety and reliability in various environments.

Despite its powerful capabilities, the BEC12S-PRO is compact and lightweight, measuring just 35x24x5.5mm and weighing only 5g, making it ideal for space-constrained applications in UAVs, drones, FPV systems, and robotics.
