Product description

KONTRAC GP550AC is a propulsion converter for electric multiple units for use on 25 kV, 50Hz catenary supply line. The converter is installed on more than 20 EMUs for Croatian Railways (HŽ) and one prototype for Railways of the Federation of Bosnia and Herzegovina (ŽFBH), the 92 units in total.
KONTRAC GP550AC converts the power from transformer outputs of AC network into propulsion power for the traction motors. The converter input current is in phase with the input voltage and with low harmonic content. During braking, the converter feeds back energy to the network. All control, protective, communication and monitoring functions are implemented in one control electronic, inside the converter.
