Matek Power Module PM12S-4A
by Matek Systems

The Matek PM12S-4A Power Module delivers reliable dual step-down voltage regulation for RC planes, drones, and UAV systems. With a wide 9V–55V input range and TVS protection, it ensures stable performance in demanding applications. OUT-1 offers selectable 5V, 6V, 7.2V, or 12V outputs with 4A continuous/5A peak current, controllable via PWM. OUT-2 provides a fixed 5V at 4A continuous/5A peak. Compact and lightweight at only 18g, this module is ideal for powering flight controllers, servos, and peripherals. Designed for efficiency, durability, and ease of use, it’s a must-have for advanced RC setups.
