Feature:1. Selected Material: The controller housing is made of aluminum alloy, with a recessed design for good heat dissipation characteristics to protect the internal circuit, from thermal overload.2. Good Performance: The brushless motor controller provides stable speed and sensitive control of braking and directional changes.3. Scope of Application: The sine wave brushless controller is applied to electric vehicles, electric bicycles, electric tricycles.4. Durable: All wires are made of high temperature resistant and flame retardant wires, which are safer. The reinforced screws are durable, and each screw is fixed with waterproof thermal conductive glue, and the waterproof effect is better.5. Low Noise: Quiet and low noise design, which is safe and worry free, no noise pollution, safer. Don't worry about disturbing others when you use it.Specification:Item Type: Electric Bicycle Brushless ControllerProduct Material: Aluminum AlloyGross Weight: 528g / 18.62ozVoltage: 48V/60V/72VPower: 600WCurrent Limit: 301APhase Angle: 60/120Turning Voltage: 1.1-4.2VUndervoltage: Automatic.1pc electric door lock2pcs positive and negative poles of the power supply3pcs motor phase wires1pc anti theft alarm wire (red: positive, black: ground)1pc anti theft alarm line (orange: anti theft electric door lock, blue: anti theft signal, green: sensitivity line)2pcs Three mode default pink line1pc high battery brake (purple: high electric brake signal)1pc low battery wire brake (yellow: level brake, black: ground wire)1pc button three speed cable (pink: button signal, black: ground)1pc reversing (gray: reversing signal, black: 1 ground wire)1pc motor hall (red: 5V positive, black: ground, yellow: green and blue hall)1pc gear shift (blue: low speed signal, brown: high speed signal, black: ground wire)White line blackhead: 2pcs learning lineOrange line blackhead: 1pc cruise lineGreen wire transparent head: 1pc meter wireBlue and white line transparent head: 1pc LCD instrument line1pc low battery brake cable (black: bottom wire, yellow: low battery brake signal)Three wire switch (red: 5V positive, green: signal wire, black: ground wire)Cruise line (1 white line blackhead + 1 orange line blackhead)Pink line white head (dual mode three mode switching line)Package List:1 x Motor Brushless Controller
