T-Motor AT 40A 4S Speed Controller

Product Description: The T-Motor AT 40A 4S Electronic Speed Controller (ESC) is a reliable solution for mid-to-high-end RC models and drones. This unit, designed by the T-Motor brand, is built to work with powerful batteries and ensures stable operation of drive systems under intense loads. It combines compact size, low weight, and a set of protective and programmable functions, making it an excellent choice for many multirotor platforms and modeling applications.

Key Features

• 4S LiPo Battery Support (14.8V): Specifically designed for 4S battery power, providing the necessary power for more demanding motors.
• 40A Continuous Current: The AT 40A guarantees a continuous output current of 40A for stable motor operation under load.
• Short-term Peak Current: The device withstands short-term peak loads above its nominal rating, which is crucial during sudden maneuvers or initial accelerations.
• Integrated BEC: The built-in linear BEC provides stable voltage and current to power the receiver and servos without the need for a separate power source.
• Dimensions and Weight: Compact dimensions of approximately 72 mm × 32 mm × 10 mm and a relatively low mass allow for easy integration of the controller into various frames and designs without significantly impacting the model's overall weight.
• Protections and Programmable Functions: Built-in overvoltage and overheating protection mechanisms, support for braking mode, and soft start make operation safer and more convenient.

More on Application

The T-Motor AT 40A 4S controller is suitable for multicopters, light aircraft, and other RC models where a combination of power and reliability is required. Thanks to 4S battery support and the ability to withstand peak loads, it works effectively with medium and high-power motors. The integrated BEC simplifies the model's electrical circuit, providing power for the receiver and servos without additional modules.

Advantages of Choice

• High reliability from the renowned manufacturer T-Motor.
• Balance between compact size and performance (72×32×10 mm).
• Easy integration thanks to the built-in BEC.
• Presence of protections and programmable modes for safe operation.
