Bel Fuse LRSA32-15-900

The LRSA product series is a power supply system specifically designed for railway and metro applications. The system complies with applicable railway standards, primarily including EN 50155, EN 50121-4, and the corresponding AREMA standards. The power supply system is designed to accommodate special LR converters, such as the LR2320-9 or LR2540-9. One of its key features is the enhanced voltage isolation (3000 VAC) between the outputs, alarm signals, and the metal enclosure (or ground). The system consists of a rack that accommodates up to 6 converters, allowing redundant configurations in terms of input and output power. Transfer relay contacts are provided to monitor output voltage functionality. A disable function is provided for remote on/off control.
