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 users 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 startupdirect startup b, Braking: Reverse load quick brakingfree braking c, Adjustable Timing: Smallmediumlarge d, Low Voltage Protection: Lowmediumhigh e, Battery Types: Lithium nickel chromeNIMHplumbic acid 6. 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. Specification: Rated voltage: DC 6-12.8V Current rating: 32A (within 5s, max current can not exceed 40A) Nominal power: 360W Rated Power: 5V 0.5A Temperature protection: 110C Speed range: 8~98 For motor poles: 2-18 pole Start: flexible startimmediate start Brake: reverse load no brake Speed signal: 8KHz16KHz fixed frequency PWM Package included: 1set x Brushless Motor Speed Controller Drive(No retail package)
