5 From Krefeld all over the world Around 100 employees in the Krefeld Mobility plant develop auxiliary converters. It goes without saying that many of our products end up in their own vehicles, but many other vehicle manufacturers also appreciate the outstanding auxiliary converters from the Lower Rhine for their rail vehicles, from high-speed trains to trams. Lead Factory Traction Nuremberg In our Lead Factory in Nuremberg, around employees develop and manufacture travel drives and motors for rail vehicles. Complete system tests for all traction equipment are carried out in our special on-site test facilities. St. Petersburg (Russia) Krefeld (Germany) Tianjin (China) Nashik (India) Alpharetta (USA) Nuremberg (Germany) Alpharetta, Georgia, USA: specialized in converters The Alpharetta plant produces complete drive solutions for the North American rail market. The innovative and proven products offer the highest level of reliability with minimal maintenance costs. The product portfolio includes converters, motors, gearboxes and auxiliary power supplies. The products are developed on a project-specific basis in order to meet customer requirements. Auxiliary and traction converters from Nashik, India The Nashik plant has been an important technology location for Siemens since 1987: Auxiliary and traction converters are developed and manufactured here. In addition, there are electrical control cabinets, drives and rail automation products as well as the development of test equipment. St. Petersburg: Motors and drives for the Russian market The plant, founded in 2006, specializes in the development, manufacture and maintenance of high-voltage motors and frequency converters for Transneft and RZD (Russian railways), among others. The portfolio also includes traction motors and converters as well as auxiliary converters, drives and APS for infrastructure applications. Tianjin plant, China The Tianjin plant is our center for electrical rail components in China and produces large electric motors and converters.

The location was inaugurated in 1995 and currently employs around 140 people. 5

6 Auxiliary converters (e.g. for local vehicles and regional trains) Advantages + + Reliable and robust + + High performance with compact dimensions + + Lower line losses due to less wiring and shorter cables + + High efficiency main fan Auxiliary converters work with forced air cooling, which reduces their weight and yours Cuts costs. The high-performance air filters reduce the need for maintenance and the acoustically optimized design as well as the perfect fan speed control keep the operating noise low. Output converter low voltage unit The low voltage unit consists of a 3 AC converter and a battery charger. It is built in a highly integrated manner and has all the necessary filters for the delivery of a perfectly sinusoidal output voltage. High switching frequencies and the compact design ensure an optimal power / volume ratio and minimal power losses with an easy-to-integrate module. Local power supply (3 AC 400 V 45 kva / 63 A) For operation and maintenance, the auxiliary converter can be supplied with a 3 AC 400 V voltage from the local network via the busbar of the train. The auxiliary converter takes up the voltage, in turn feeds the 110 V DC voltage network and charges the vehicle batteries. 6th

7 Master Control Unit The Master Control Unit takes over and monitors all essential functions of the auxiliary converter. It is connected to the inverter controls inside via CAN and to train communication via MVB or Ethernet. The Master Control Unit offers a large number of digital and analog input and output ports and can thus be adapted to all project requirements. High-voltage input converter unit The high-voltage input converter unit impresses with its compact design, potential isolation between input and output as a standard safety function, and integrated sensors and magnetic components in an easy-to-integrate control module. Pre-charging unit In order to limit the inrush current and enable a smooth start-up, the unit always starts up with a pre-charging resistor (which is switched off during normal operation). Input filter The input filter ensures the input impedance and limits the interference current that is normally generated by high-frequency inverters (IGBT) in order to prevent interference on the line and input side. 7th

8 Areas of application for our auxiliary converters Our auxiliary converters work in all types of rail vehicles and coaches, provide the on-board voltage for 3 AC / 1 AC electrical devices as well as the DC supply and also charge vehicle and supply batteries quickly, reliably and safely. The systems do not necessarily have to be installed on board, but are also used stationary, as is the case with our charging systems for electric buses. 8th
