Feature: With micro single-chip system, this speed control can achieve simple system programming, which can suit better high speed high power brushless motors. It has several features:1. Safety starting: to avoid injury, the motor will not start immediately if the speed governor potentiometer is not in the lowest gear, which is necessary, for high speed high power motor, to protect the safety of the user.2. Thermal Protection: The speed control has an aluminum heat sink that allows it to work continuously at 30A. When the temperature reaches 110 degrees Celsius, the temperature detection system will send a protection signal, and the system will automatically reduce the output power by 60% to protect the speed control and motor. It will return to normal power when the temperature is lowered. To protect the actuator module, heat should be dissipated during long-term use.3. Signal loss prevention: automatic closure when no signal from the generator is detected PWM signal (potentiometer).4. Power Identification System: The speed control has a power identification system, which is designed for high-speed high-power engines such as model aircraft. Not suitable for low-power brushless motors.5, Programming functions: With single-chip control system, some functions can be changed:A, Starting: Flexible slow starting/Direct startingB, Braking: Reverse load Fast Braking/Slow BrakingC, Adjustable Time: Small/Medium/HighD, Undervoltage Protection: Low/Medium/HighE, Battery Types: Lithium/Chromium Nickel/NIMH/Plumbic Acid6. Return to factory settings: the wrong operation may be cleared7. Other functions (please ignore if only used to drive the motor): external PWM signal generator can send signal to control the speed or to turn on the control system, therefore it can test the control system s less than 55g.
