OOTDTY 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 functions:1.Safety Startup: To avoid any injury, the motor will not start up immediately if the potentiometer of speed controller is not at the lowest gear, which is necessary for high-speed high-power motor to protect user's safety.2. Temperature Protection: The speed control has aluminum heat sink, which allows it work at 30 A continuously. When temperature reaches 110 celsius degree, temperature detect system will send a protection signal and system will auto decrease 60% power output to protect speed control and motor. It will back to normal power after temperature is decreased. To protect the actuator module, please dissipate heat during long-time using.3. The signal loss prevention: Auto shut down when there is no signal detected from PWM signal generator(potentiometer ).4. Power Identification System: The speed control has power identification system, which is designed for high-speed high-power motors such as in model plane. It is not suitable for low-power brushless motors.5, Programming Functions: With single-chip control system, some functions could be altered:a, Startup: Flexible slow startup/direct startupb, Braking: Reverse load quick braking/free brakingc, Adjustable Timing: Small/medium/larged, Low Voltage Protection: Low/medium/highe, Battery Types: Lithium /nickel chrome/NIMH/plumbic acid6. Back to Factory Settings: Wrong operation can be cleared 7. Other Function(please ignore if only used for motor drive ) : The external PWM signal generator can send signal to control speed or to turn steering gear, therefore it can test steering gears less than 55 g.
