In July, 2015 the design office of Transconverter JSC started the development of a new version 01 of ZUT105-01 U1 traction charging device for EKA-05 electric locomotives.

ZUT105-01 U1 traction charging device is designed for transformation of 825 V DC of subway overhead system or 400 V 50 Hz three-phase voltage of depot electric network in adjustable DC voltage, which is necessary for charging/additional charging traction battery with a rated capacity of 1040 А·h and a rated voltage of 432 V, mounted on EKA-05 electric locomotives.

As distinct from the previous version the developed ZUT105-01 U1 traction charging device will feature built-in power diodes of recuperation of EKA-05 electric locomotive traction drive.

ZUT105-01 U1 maximum output power is 105 kW.

Charging device is mounted under the body of EKA-05 electric locomotive.

CAN is used for information exchange between charging device and TCSM.
