ABB IGBT VVVF | Class 399 Traction Sound | PWM Inverter - Class 399 Inductor Recording

The Bordline CC400 MS is an impressively compact traction converter and 800PEC TCU package. It works with 600VDC, 750VDC, and 25kVAC. Not only can it drive the motors, it can also deliver auxiliary power in AC and DC while it charges batteries - making it an AIO converter. The CC400 MS is also water-glycol liquid cooled and housed in an IP65 container.

The Vossloh Class 399 is a dual-voltage Citylink tram-train featuring materials supplied by Stadler Rail and ABB traction transformer for running on the Hallam line towards Rotherham and Parkgate. It functions as both a tram, but is also fitted with the necessary equipment to run on mainlines. This includes the electrical systems, but also the safety systems and radio. The tram-train is still the size of a tram however, so at stations such as Rotherham, lower platforms are provided at the railway station next to the full height platforms for commuter rail trains.

PWM modes are thought to be: 1000Hz, 1400Hz, 1800Hz, 7P
