This isn't your typical off the shelf Kelly or Sabvoton.

The Mobipus 72600 Permanent Magnet Synchronized Motor controllers deliver robust power unlike any previous vehicle control system. They provide unprecedented flexibility and power through inclusion of a field-programmable logic controller embedded in a state-of-the-art motor controller.
The embedded logic controller runs a fully functional adoptive-oriented DC Permanent Magnet Synchronize Motor control operating system (OS) that can be user-tailored via parameter modification.

The OS also contains logic to communicate with OEM developed software via industrial RS485 bus, that can be used to enhance the controller capabilities beyond the basics.
Wide range of adjustable parameters are available for customer’s application demand, in order to redefine controller’s behavior to meet varies working environment. Parameters may be adjusted by using PC with Mobipus Motor Controller Control Console, and real time system information monitoring and logging is displayed in the software console.

There is also an optional wifi programming module (75AUD) as well as a mechanical throttle interface for cable actuated motorbike throttles. Also offered is a range of water cooled and ambient heatsink backing units ($100AUD and $50AUD respectively). Please contact us for confirming payment and pricing. 

Note that the model shown has an added liquid cooled back using standard PC cooling circuit connections for heat dissipation during extreme use.

For an additional $100 AUD we can organise a one to two hour configuration session with myself to ensure that this controller matches your chosen application. The ability to configure these controllers in user mode is very limited.
