Features:With the overload protection and current abnormal protection function.Has the locked-rotor protection function, if motors can not start within 5s repeatedly, module will stop output. Adjust voltage VR port to 0v or power off, the protection status can be removed,when power on again.With the soft commutation function, this function has the effect of protecting the power tube and the motor in many applications, improving the service life of the drive and motor.The function of the speed pulse signal output, depending on the motor each circle of the output pulse number is different.Enable function, EL port, high level (5v) motor work, low level (0v) motor stop.Specifications:Working voltage: 36V-72vOperating current: ≤15ADriving power: ≤700WSpeed adjustment voltage: 0v-5vPWM speed control frequency: 1KHz- -10khzWork temperature: - 40-85 ℃Work humidity: ≤90%RHDimensions: 63 x 42 x 33mm/2.48 x 1.65 x 1.29inch(control end, hall end is 2.54 socket, motor end is 3.96 socket)Wiring:VCC (power +,input36-72V)GND (power -)MC (motor phase line W)MB (motor phase line V)MA (motor phase line U)Package Included:1 x 700W Brush less Motor Controller
