SL MV Controller
35.8 kW Middle-Voltage Brushless Motor Controller
The SL MV is the flagship of the siliXcon controller family. It combines the highest power output, galvanic isolation, and middle-voltage capability into a single robust platform. This is the full package for applications that accept no compromises – heavy-duty electric powertrains, marine propulsion, and industrial systems operating at higher voltage levels.

Controller Firmware
Firmware consists of two major parts: the motor control algorithm and the application.
Both are hardware independent — scale your project without any problem. The application handles system behaviour while the algorithm controls the motor, protecting the motor, battery, and controller.
All controllers also support our scripting language. Customize existing applications or write your own logic from the ground up.
Custom Application
We can provide you a completely custom firmware solution tailored to your specific use-case requirements.
OPHION
Simple analog motor control via potentiometer or PLC — for pumps, conveyors, and servo drives.
LYNX
Complete vehicle control system for scooters, bikes, and motorbikes with built-in power maps and 500+ functions.
FALCON
RC vehicle control for drones, RC cars, and boats with servo PWM input and safety features.
ECHO
Minimal firmware with no internal logic — full motor control via CAN or UART from an external VCU.
IGNIS
Starter-generator control for hybrid and range-extender applications with cranking sequence and overvoltage protection.
