PP-MESC12AU - 12A ESC
(Brushless Electronic Speed Controller)

Specifications

Features

• Soft Starting – Reduces the stress on the airframe.
• Auto Timing – no need for manual selection.
• Self Checking
• Low Voltage Cut Off – Protect your batteries from damage due to excessive drain.
• Thermally Protected – The ESC will reduce the output power to the motor depending upon its temperature.
• Signal lost Protection – Upon loss of radio signal the ESC will stop the motor.
• Power on Protection – The motor will not start unless the throttle stick is in the off position when the power is applied.
• The ESC's come pre-programmed with soft start, brake off and medium timing which is suitable for nearly all inrunners and outrunners
• Simple Parameter Setting via the transmitter.
  

Normal Startup procedures

Step1: Pull the throttle stick to the bottom position (full Off throttle),
Step2: Switch the transmitter on,
Step3: Switch the ESC on (normally by connecting batteries).
Step4: System detects the Min. throttle signal, and makes a long “beep” sound.
Step5: System detects battery voltage and makes several short “beep” sounds, which denotes the number of battery cells.
Step6: System conducts self-check. If it is normal, you will hear a “ 1 2 3” tune, push the throttle stick to start up. (LED on the ESC will flash along with the tune.)

Throttle range setting procedures

Step1: Push the throttle stick to the top position (full On throttle),
Step2: Switch the transmitter on,
Step3: Switch the ESC on (normally by connecting batteries)
Step4: System detects the Max. throttle signal, and makes two “beep” sounds, which denotes that Max. throttle has been confirmed and saved.
Step5: Pull the throttle stick to the bottom position (full Off throttle) within 5 seconds,
Step6: System detects the Min. throttle signal and makes a long “beep” sound.
Step7: System detects battery voltage and makes several short “beep” sounds, which denotes the number of battery cells.
Step8: System self-check occurs. If it is normal, you will hear a “ 1 2 3” tune, push the throttle stick to start up.
If the system doesn’t detect the throttle signal, it will constantly make “beep” sounds without stopping.
Any fault in self-check, it will make 20 short “beep” sounds.

Protection setting

Low-voltage protection: Whether to shut down the motor immediately or to lower the power when the input voltage drops below the programmed low-voltage protection voltage depends on the values set as Cutoff Type.

Loss of signal protection: Power will automatically lower to 20% or less when signal is lost for 1 second, and resume when detecting the signal.

Over-heat protection: When the temperature increases to above 110 Celsius degree, power will be lowered gradually to less than 35% of the full power, and will resume when the temperature decreases.

Hardware self-check: The system will check by itself when the battery is connected. Any hardware fault, it will make 20 short “beep” sounds.
