BEC20S-PRO, 7-85V To 5V/8V/12V-5A

Product Title

Matek BEC20S-PRO 7-85V 5A Synchronous Buck Regulator | 3-20S LiPo BEC Power Module 5V/8V/12V Selectable Output for FPV Drone VTOL UAV

Product Description

The Matek BEC20S-PRO is a high-voltage wide-input synchronous step-down BEC module built for high-power RC, FPV and VTOL drone projects. It accepts an ultra-wide DC input from 7V to 85V DC, perfectly compatible with 3S–20S LiPo batteries, making it the ideal power solution for large long-range UAVs, heavy-lift drones and industrial RC platforms.

You can select your target output voltage simply by solder jumper: 5V / 8V / 12V, with a steady continuous 5A output (peak 9A). High synchronous buck design delivers excellent conversion efficiency up to 96%, low heat generation and tiny output ripple, to keep your flight controller, VTX, camera and servos powered reliably.

Compact PCB size only 35mm × 24mm, with 3.81mm pitch terminal pads for easy wiring. Integrated protection circuits guard against over-current, over-temperature and short circuit, greatly improving reliability for long-endurance flight missions.
