Description The Mateksys Power Module PM12S-4A is engineered for unmatched efficiency, offering a wide 9V–55V input range with TVS protection and dual independent step-down voltage regulators. With selectable output options up to 12V, PWM controllable ON/OFF function, ultra-low ripple, and a lightweight compact design, this powerhouse ensures stable, reliable, and customizable performance for your drones, RC models, or electronic projects where precision and dependability are non-negotiable. Specifications Wide 9V to 55V Operating Input Range with TVS protection 2x independent Step-Down Voltage Regulators OUT-1 Vx, 5V / 6V / 7.2V / 12V output options(5v default). 4A continuous, 5A Peak. ON/OFF is controllable by PWM signal. OUT-2 5V (Fixed), 4A continuous, 5A Peak Output ripple: 20mV (VIN=50V, Output 5v @ 4A), 40mV (VIN=50V, Output 12V @ 4A), Size & Weight: 50 x 32 x 7mm, 18g Packing: 1x PM12S-4A (no wires) Settings 1. Set the OUT-1(Vx) voltage 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. 2. PWM control 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. Product Includes 1 x Mateksys Power Module PM12S-4A
