Controller spec.:

Matching Motor type: BLDC Motor with Hall sensor

Matching Motor power: 2000W-3000W

Voltage range: 36V-72V

Support Regen Function

Support Programmable with various functions

Support Multi-Regenerative Functions:

1. Regen when Braking

2. Regen when taking off the Accelerator

3. Regen with a simulative Pedal

KLS controller is supposed to reduce the noise of BLDC motor,especially for hub motor.The BLDC motor must be based on 3 hall sensors.Customers can program the KLS controller on PC software or Android App.You may need a Z-TEK USB to RS232 cable for programming the controller if you want to program the controller on Android Tablet.

You have to do Identification angle operation before running the motor for the KLS Controllers.  And it can be done by PC Program or Andriod App(Though Blue-tooth adaptor).

The details progress will be showed in the Manual of the KLS Controller.


1)Intelligence with powerful microprocessor.
