SpecificationsBrand: MatekSysModel: PM12S-4A Voltage Input Range: 9-55V DC (3-12S LiPo)Output 1: Adjustable Voltage (5V/6V/7.2V/12V), 4A continuous, 5A peakOutput 2: Fixed Voltage (5V), 4A continuous, 5A peakOutput ripple: 20mV (VIN=50V,Output 5v @ 4A),40mV (VIN=50V,Output 12V @ 4A),PWM Control Frequency: 50Hz-330Hz, 900-2100SizeWeight: 50 x 32 x 7mm, 18gPacking: 1x PM12S-4A(no wires)Settings:1. Set the OUT-1(Vx) voltageOutput voltage indicators, 5V Red, 6V Green, 7.2V Green, 12V BluePress 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 controlPWM FreqRange:50Hz-330Hz, 900-2100OUT-1 Default output is ON if no PWM signal connectedConnect 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.Package Included:1 x PM12S-4A Power Module
