LRSA Series

The LRSA product series is a power supply system designed for railway and subway applications. The applicable railway standards, mainly EN 50155, EN 50121-4, and the respective AREMA standards are observed. The power supply system is designed to accommodate standard LR series converters, such as LR2320-9 or LR2540-9. A main feature is the enhanced voltage isolation (3000 VAC) between outputs, alarm signals, and the metallic chassis respectively the ground. The system consists of one rack. The rack can accommodate up to 6 converters, which allows redundant configuration in terms of input and output energy. A change-over relay contact is available to monitor the function of output voltage. Inhibit function is available to remote on/off.
