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:
- 12% 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 th eelectric locomotive.
