Reversible converters with 4000 and 5600kW power for AC electric locomotives

Reversible converters of VIU series are used to convert overhead system AC power into DC power required to feed traction electric motors. 

VIU-5600 is applied to electric locomotives VL 65, EP1М, EP1P.

VIU-4000М is applied to electric locomotives VL 80R, VL80M, 2ES5K, 3ES5K.

VIU-4000-2M with axle-by-axle rod adjustment is designed for 4ES5К – the most powerful electric locomotive in the world.

Converter is used to ensure:

  • Significant increase of electric locomotive resource due to non-contact control regulation;
  • Locomotive traction increased no less than 12%;
  • Saving up to 15% of electric power consumed by the electric locomotive.

Designed to comply with RoHS and REACH requirements.
