In September 2021, Transconverter LLC manufactured two pulling charging converters ZUT105 01 Y1 for an electric train of an overhead line-battery type EKA 05.

A charging converter ZUT105 01 Y1 is meant for conversion 825 VDC voltage of an underground overhead line or three-phase voltage 400 V 50 Hz of a depot electrical grid to a regulated DC voltage which is necessary for charging/recharging of traction battery with nominal capacity 1040 A h and nominal voltage 560 V installed on the electric train of the overhead-line battery type EKA-05.

The charging converter is installed under the cargo body of the electric train EKA-05.

A CAN bus is provided for data exchange between the charging converter and the control system of the electric train upper level.
Currently 6 charging converters ZUT105 01 Y1 are in service.
