Matek Power Module PM12S-4A 9-55V Input 5V/6V/7.2/12V
£19.99
The Matek PM12S-4A Power Module delivers clean, reliable power for larger builds running up to 12S. With a wide 9–55V input range and two independent 4A BECs, it’s a flexible solution for powering flight controllers, peripherals, servos, lighting systems, or onboard electronics.
It features a fixed 5V/4A regulator plus a second selectable-output BEC that can be set to 5V, 6V, 7.2V or 12V using the onboard button. OUT-1 can also be switched remotely via a PWM channel, letting you control accessories such as lights or gimbals directly from your radio.
Despite its capability, the PM12S-4A is compact and lightweight, making it ideal for larger multirotors, planes, and long-range platforms that need robust voltage regulation without added bulk.
Features
- 9–55V DC input (3–12S LiPo), TVS protected
- 2× independent step-down regulators
- BEC Vx: 5V / 6V / 7.2V / 12V, 4A cont., 5A peak, PWM-switchable
- BEC 5V: 4A continuous, 5A peak
- Low-ripple outputs (20–40 mV)
- 50 × 32 × 7 mm, 18 g
- Settings
- Output voltage indicators, 5V Red, 6V Green, 7.2V Green, 12V Blue
- Press and hold the button for 3 seconds to enter the setting of the OUT-1 voltage.
- The LED on the current output voltage will blink. then press button to choose the voltage between 5V(Red), 6V(Green), 7.2V(Green), 12V (Blue) .
- The value will be saved if no button action within 3 seconds.
- PWM Freq & Range: 50Hz-330Hz, 900-2100
- OUT-1 Default output is ON if no PWM signal connected
- Connect the PWM pin and GND to a spare PWM channel on the receiver or flight controller.
- OUT-1 will be turned OFF when the auxiliary switch’s pwm value becomes higher than 1800. It will be turned ON when the value falls below 1200.
