SEM-04 is designed to control a DC traction electric drive.
SEM-04 provides control over the process of converting mechanical energy generated by a diesel engine into electrical energy and converting electrical energy back into mechanical energy, which is used in the form of adjustable traction and braking forces on the driving wheels of the vehicle. control signals for the power circuit contactors of the electromechanical transmission. protection for powertrains. Forms a log of accidents.
