AM controller series

Up to 51V (12S Lithium battery), up to 2,3 kW nominal power, up to 4 kW peak power.

The AM is the lightest standard member of the ESC3 controller family. It can be used in wide range of applications, especially in industry and automotive. Using most modern technologies it achieves extreme dynamics and maximal effectivity, it implements smooth start or regenerative braking, all this with minimal dimensions. The AM controller is capable of driving all common types of electric motors.
