Mateksys Micro BEC 6-60V to 5V/9V/12V

The Mateksys Micro BEC is a synchronous step-down voltage regulator designed to supply clean, isolated power to video transmitters, cameras, and flight electronics. Supporting a 6V to 60V input range, this regulator handles direct battery connections from 2S all the way up to 14S LiPo packs. It suits everything from standard 5-inch freestyle quads to high-voltage X-Class and heavy-lift cinelifter builds.

Key features

• Steps down high-voltage flight packs to power standard 5V, 9V, or 12V FPV electronics.

• Output voltage is configured via a simple solder bridge (ships defaulting to 5V).

• Maintains a continuous 1.5A load with brief 2.5A burst capabilities.

• Integrates thermal shutdown, over-current protection, and a 3-second short-circuit tolerance.

• Compact footprint adds minimal bulk to tightly packed electronics stacks.

Wiring a dedicated BEC isolates power-hungry components like a digital air unit or a high-power analog VTX from the flight controller's internal regulator. This bypass prevents flight controller brownouts during heavy throttle punches and reduces electrical noise in the video feed.
