900W/1800W High Power Brushless Motor Drive Sensor/Sensorless DC Motor Controller for Three-phase Brushless DC Motor with Hall High power brushless motor drive controller, which can control the pump, oil pump, air pump, fan driven by the three-phase brushless DC motor, can also be used for lawn mower, Marine thrusters and other high power motor drive occasions. Two controller voltage ranges are available on demand: A suitable for voltage range DC 11V~30V brushless motor (common 12V/24V), B suitable for voltage range DC 20V~60V brushless motor (common 24V/36V/48V), A maximum current 40A maximum power of 900 watts, B maximum current 40A maximum power of 1800 watts (Note: The maximum power is related to the supply voltage). The controller is dual-mode, with Hall line (hall line can not be connected), inductive and non-inductive motor can be used, through the potentiometer stepless speed regulation, customers can also be replaced by electric vehicle handle speed regulation, speed regulation is 0~5V voltage signal, does not support PWM speed regulation, if you want to use PWM speed regulation can consult the owner, the controller is equipped with positive and negative switching switch, The middle position of the switch is to stop, can be reversed to switch direction, reverse does not limit the speed, speed regulating potentiometer at any position can be started directly.
