Matek BEC12S-PRO — Professional High-Voltage Power Regulator for UAVs
Matek BEC12S-PRO is a highly reliable DC-DC converter for powering drone onboard electronics up to 12S LiPo (50.4V). The module is designed for FPV platforms, industrial multicopters, and autonomous robotic systems that require stable, clean, and overload-protected voltage.
The BEC supports three fixed output options: 5.2V, 8V, or 12V, which can be selected for specific tasks — powering flight controllers, servos, video transmitters, amplifiers, and other electronics. With an efficiency of 88–96%, the module minimizes heat and losses, ensuring long-term stable operation.
Built-in protections include TVS protection, overload protection, short-circuit protection, overheat protection, and automatic recovery after critical conditions. The materials and component base meet high reliability requirements for RC modeling and industrial systems.
