$495 plus shipping
This controller was part of a EV science project (total use time of the controller was less than about 1 hour). I can show you the project if you like. If the controller fails to work, I will refund your money.
The Millipak™4Q controller operates in full 4-quadrant mode allowing contactor-free operation in direction changing and regenerative braking. It operates in either torque or closed loop speed control mode.
The Millipak™4Q permits adjustable regenerative braking without the use of additional electronic circuitry and contactors.
