[Zum Premium-Modellbau Shop](https://www.premium-modellbau.de/search?sSearch=PM-7222)

\_x000D\_\* Wide 9V to 55V Operating Input Range with TVS protection \_x000D\_\* 2x independent Step-Down Voltage Regulators \_x000D\_\* OUT-1 Vx, 5V / 6V / 7.2V / 12V output options(5v default). 4A continuous, 5A Peak. ON/OFF is controllable by PWM signal. \_x000D\_\* OUT-2 5V (Fixed), 4A continuous, 5A Peak \_x000D\_\* Output ripple: 20mV (VIN=50V, Output 5v @ 4A), 40mV (VIN=50V, Output 12V @ 4A), \_x000D\_\* Size & Weight: 50 x 32 x 7mm, 18g \_x000D\_\* Packing: 1x PM12S-4A (no wires) \_x000D\_ \_x000D\_

#### Settings

\_x000D\_

**1. Set the OUT-1(Vx) voltage**

\_x000D\_

\_x000D\_\* Output voltage indicators, 5V Red, 6V Green, 7.2V Green, 12V Blue \_x000D\_\* Press and hold the button for 3 seconds to enter the setting of the OUT-1 voltage. \_x000D\_\* 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) . \_x000D\_\* The value will be saved if no button action within 3 seconds. \_x000D\_ \_x000D\_

**2. PWM control**

\_x000D\_

\_x000D\_\* PWM Freq & Range: 50Hz-330Hz, 900-2100 \_x000D\_\* OUT-1 Default output is ON if no PWM signal connected \_x000D\_\* Connect the PWM pin and GND to a spare PWM channel on the receiver or flight controller. \_x000D\_\* 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. \_x000D\_ \_x000D\_
