Rail Charging Converter
Powering the future of sustainable rail with Sitras RCC
Powering the future of sustainable rail with Sitras RCC
As railway systems transition to sustainable operations, a robust and efficient charging infrastructure for battery-powered trains becomes essential. The Sitras Rail Charging Converter (RCC) charges battery-powered trains and supplies reliable power to depots, test tracks, and lab settings. Our technology helps rail operators accelerate their shift to cleaner, electric traction.
Sitras RCC converts the local medium-voltage grid (three-phase) into a single-phase traction power supply, typically at 25 kV/50 Hz or 15 kV/16.7 Hz. With a rated power of 2.5 MVA, the system is scalable, allowing you to connect multiple converters in parallel to meet higher operational demands.
