SC controller series

Up to 84V (20S Lithium battery), up to 12,6 kW nominal power, up to 18 kW peak power.

The SC is an ESC3 family controller with an excellent performance-to-weight ratio. It can be used in wide range of applications, especially in industry and automotive. Using most modern technologies it achieves extreme dynamics and maximum efficiency, it implements smooth start or regenerative braking, all this with minimum dimensions. The SC controller is capable of driving all common types of electric motors.
