The Bel Power Solutions LRSA08-28-900 is part of the LRSA Series AC-DC Subrack System, engineered for railway and subway applications. This enclosed power supply system features a 19-inch rack mount design with convection cooling, ensuring reliability in harsh environments.
Key electrical specifications include a wide input voltage range of 90 to 264 VAC at 50 to 60 Hz, delivering up to 224W of power. It offers an output voltage of 12 VDC with a nominal current of 10A, and also supports an 8A output current. The system boasts high efficiency up to 92% and a power factor greater than 0.93, meeting IEC/EN 61000-3-2 harmonics standards.
Designed for enhanced safety and performance, the LRSA08-28-900 provides 3000 VAC isolation voltage between outputs, alarm signals, and chassis ground. It operates reliably within a temperature range of -40°C to 71°C. Features include active output current sharing, output voltage monitoring with change-over relay contacts, inrush current limitation, hot-swappable capability, and an inhibit function for remote on/off control.
This subrack system is safety approved to UL/CSA 62368-1 and IEC/EN 62368-1 standards. Its rugged design and compliance with railway standards like EN 50155 and EN 50121-4 make it suitable for critical infrastructure applications.
