AcxicoAcxico 1Pcs DC12V 30A High-Power Brushless Motor Speed Controller DC 3-Phase Regulator PWM Controller Driver
Main highlights- With micro single-chip system, this speed control can achieve simple system programming, which can suit better high-speed high-power brushless motors.
- The signal loss prevention: Auto shut down when there is no signal detected from PWM signal generator(potentiometer ).
- 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.
- 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.
- 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.
