Efficient On-Board Electrical Systems to Supply Power to Railway Vehicles and Commercial Vehicles

Jenoptik develops on-board electrical systems that reliably supply your railway vehicles or commercial vehicles with electrical energy so that you no longer have to rely on the infrastructure for a power source.

Our on-board electrical systems are compact, highly efficient, and specifically tailored to the demands of railway technology. The latest diesel motors produced by various manufacturers are used to drive the systems. The units reliably supply energy to the on-board system independently of the on-board motors or external sources such as overhead lines.

You control the on-board electrical system using defined analog or digital interfaces with an integrated electronic control unit that can be used to individually set all the necessary protection, operating, and monitoring components.

Our experts will develop an unit specifically designed for your requirements|. To minimize the energy consumption of the unit, we ensure that all the individual components such as the control cabinet, cooler, and exhaust gas treatment are perfectly matched. We take into account the customer's specifications such as the installation space, environmental requirements, and efficiency on all projects. We then develop the ideal solution for our customers, taking into consideration all commercial and technical factors. Our units achieve an output power of up to 2000 kW at output voltages of up to 2700 V AC or 3600 V DC. Diesel motors produced by various manufacturers are integrated into our units. All units comply with the applicable standards.
