In April 2024, “Transconverter” set about manufacturing two charging devices of ZUT105‑02 U1 type for electric locomotive EKA‑05 type.

The charging device ZUT105‑02 U1is meant for charge/recharge of traction battery with a nominal capacity of 1040 Ah and a nominal voltage of 560 V, which is set on the electric locomotive EKA‑05 type. Unlike the ZUT105‑01 U1, this device will contain a new modern charging unit.

ZUT105‑01 U1 has an input voltage 825V DC of the underground power circuit and a three-phase 400V 50Hz of the depot electric circuit.

The maximum output voltage of ZUT105‑01 U1 is 105 kW.

The charging device is installed under the body of an electric locomotive EKA‑05.

A CAN bus is provided for the exchange of information between the charging device and the upper-level control system of the electric locomotive.

Currently, there are 9 charging devices of a similar type in operation.
