Matek Servo PDB with 12A BEC (9–55V to 5/6/8V, 12S)

The MATEKSYS Servo PDB with 12A BEC is a dedicated buck regulator for powering servos on large-scale fixed-wing aircraft and heavy-lift multirotors, isolating noisy, high-current servo draw from a flight controller's own BEC.

Key features

• Accepts a wide 9–55V (3–12S LiPo) input and steps it down to a user-selectable 5V, 6V or 8V servo rail.
• Synchronous buck design runs at 88–96% efficiency, keeping the board cool under sustained servo load.
• Delivers 12A continuous with a 20A peak, enough for several standard or digital servos on one rail.
• Thermal shutdown, self-recovering overcurrent protection and 2-second short-circuit tolerance protect the board and wiring.
• Compact 50 x 27 x 8mm board weighs 18g, with pins shipped unsoldered so you can angle them to suit your build.

Specifications

• Input voltage: 9–55V (3–12S LiPo)
• Output voltage: 5V / 6V / 8V (selectable)
• Continuous current: 12A
• Peak current: 20A
• Size: 50 x 27 x 8mm
• Weight: 18 g

This board has no reverse-polarity protection, so double-check input wiring before powering it up. Best suited to fixed-wing and heavy-lift platforms whose flight controller lacks a dedicated high-current servo BEC.
