Features 1Designed for highpower brushless motor 2Rated Voltage:DC612.8 V, Rated current: 30A 3Rated power:5V 0.5A, Temperature protection:110 4Speed control range:8%-98% 5Speed control signal:8 KHZ / 16 KHZ fixed frequency PWM Specification This controller is designed for high power brushless motor. It is small but has many functions, including steering gear test function. 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, 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 startup b, Braking: Reverse load quick braking/free braking c, Adjustable Timing: Small/medium/large e, Battery Types: Lithium /nickel chrome/NIMH/plumbic acid 6. Back to Factory Settings: Wrong operation can be cleared 6. 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. Specifications: Rated Current: 30A(no higher than 40 A) Rated Power: 5 V 0.5 A Temperature Protection: 110 speed Control Range: 8%-98% Suitable Number of Poles: 2-18 Startup Methods: Flexible slow startup/direct startup Braking Mode: Reverse load braking/without braking speed Control Signal: 8 KHz / 16 KHz fixed frequency PWM Steering Gear Test Function: Below 55 g Packaging list: 1 x Speed Controller 1 x Electric Control Board Note: New-style and old-style are shipped randomly.
