Product parameters: Condition: 100% brand new Item type: Brushless Motor Controller Material: Aluminium alloy and plastic Voltage: 36V-84V Power: 100W-1500W Max Current limit: 50A 12-tube sinusoid controller,Normal Instrument line, a Sine wave model only can work with brushless DC motor . If motor doesn't have hall sesnor or hall sensor is damage .it is square wave controller . 1. 36V 48V 60V 72V 84V universal 2. One-line instrumentation adds more adaptability, about 80%. 3. In terms of hardware: thicker aluminum shell, better heat dissipation. The motherboard solution is better. Power tubes, capacitors, copper bars, etc. are better. 4.Suitable Motor Phrase Angle: 60/120 Phase Angle Universal 5.Suitable for: electric bicycle, scooter,Small tricycle,Two-wheeler etc 36V-84V 800W-2000W sine wave brushless controller function: 1.hall line 2.low brake 3.differential motor dedicated 4.anti theft power supply 5.anti-theft signal 6.key lock 7.Multi data instrument cable 8.reverse 9.3-speed 10.Intelligent recognition?self-learning line) 11.cruise 12.throttle 13.Phase line speed display 14.high brake 15.Hall speed speed display how to connect ? 1. connect the battery 2. connect the controller throttle line?color to color) , connect electric lock ?if your throttle not have key lock, controller key lock can be shorted) 3. connect the hall line(if motor without hall line, don't need connect) 4.docking the two intelligent recognition lines, the wheel will forward or reverse. (1.if wheel forward ,Separate the intelligent recognition line. 2.if wheel reverse, Separate the intelligent recognition line. Docking the intelligent recognition line again, if wheel forward ,Separate the self-learning line.) 5.other functions can be connected as needed.
