Matek BEC12S-Pro, 9-55V to 5V/8V/12V-5A
by Matek Systems

The BEC12S-PRO is a high-performance DC-DC buck converter designed to efficiently step down a wide input voltage range of 9V to 55V to three selectable output voltages (5.2V, 8V, or 12V). With a default output of 5.2V, this versatile power supply is ideal for powering your drone, RC aircraft, or other high-power electronics. The BEC12S-PRO features synchronous switching, offering efficiencies of 88% to 96%, ensuring minimal power loss and better battery life. Capable of delivering up to 5A of continuous current and 9A peak current, this BEC can handle demanding loads. The unit is also equipped with built-in overcurrent protection, thermal shutdown, and self-recovery, ensuring reliable operation. With a compact design and low output ripple, the BEC12S-PRO is perfect for stable and efficient power delivery.
