FIELD: transport.
SUBSTANCE: invention relates to systems that convert constant voltage of contact circuit into multi-channel system of voltages of DC electric locomotive. Proposed system comprises circuits designed to supply excitation windings of traction motors and locomotive internal circuits, two power supply distribution lines, units of communication with microprocessor control and diagnostics system realized via two code communications lines, unit of frequency converters and safety unit. Every aforesaid distribution line comprises voltage down step controller and two static voltage converters.
EFFECT: improved electric supply of electric locomotive control systems.
