KONTRAC GP 170 DC converts 600 VDC or 750 VDC line voltage into propulsion power to control and drive asynchronous traction motors on tram vehicles. The converter supplies two asynchronous traction motors connected in parallel. The electrical motor drive operates in two modes: traction mode and braking mode.

KONTRAC GP 550 DE converts the variable voltage from diesel generator into drive power for the traction motors, three-phase auxiliary power supply for the train onboard consumers and into DC auxiliary power supply for charging train batteries and supplying of all DC consumers on board the vehicle. KONTRAC GP 550 DE is a robust and solid unit incorporating modern IGBT technology.
