SL

SL controller series

Category:

Up to 101V (24S Lithium battery), up to 24,5 kW nominal power, up to 36,6 kW peak power.

The SL is automotive grade controller from ESC3 family, it can deliver maximum power whilst keeping weight as low as possible. It can be used in wide range of applications, especially in industrial and automotive. Using the most modern technologies it achieves extreme dynamics, maximum efficiency, sensorless control or regenerative braking, all kinds of protection or galvanic isolation, all this with minimum dimensions. The SL controller is capable of driving all common types of electric motors.
