On-Board System Alternator from Jenoptik: Energy-Efficient Power Supply in Rail Traffic and for Commercial Vehicles

The reliable and robust on-board system alternators from Jenoptik are used to supply power for various vehicles in the civilian sector. We offer the widest range of designs that precisely match your application.

The on-board system alternator from Jenoptik ensures on-board power supply to railway vehicles and commercial vehicles. Reliable and powerful, it can supply power for a number of applications, such as lighting, air conditioning systems, ventilation systems, refrigerators or electric motors.

The separately excited or permanent magnet excited synchronous alternators are designed for an output power of up to 2000 kW. Their robust and low-maintenance design makes them resistant to environmental influences in the installation compartment. They are particularly compact, and extremely efficient in converting energy. As a result, you can operate the on-board power alternator extremely efficiently, while saving space reducing unnecessary weight.

Depending on how you use your on-board system alternator, Jenoptik will precisely tailor the electric and mechanical parameters to meet your requirements. The item is supplied in either a single or double bearing design, as a separately excited alternator with slip rings, in a brushless design, or even as a permanently excited alternator. The alternator is optionally cooled with air, water-glycol or oil. We also precisely adjust the output power and voltage, frequency, and packaging to meet your specific requirements. This ensures you remain flexible, and can integrate the on-board system alternators easily into your existing systems.
