The Bel Power Solutions LRS12-50-900G is an AC-DC subrack system designed for demanding railway and subway applications. It operates within a wide input voltage range of 85 to 264 VAC and supports an output current of 12A, with output voltages ranging from 15 to 50 VDC.
This system is built for harsh environments, featuring a rugged and reliable design. It complies with key railway standards including EN 50155 and EN 50121-4, as well as AREMA standards. The power supply offers enhanced voltage isolation of 3000 VAC between outputs, alarm signals, and the chassis.
Key features include convection cooling, hot-swappable capability, and a wide operating temperature range from -40°C to 71°C. The system is safety-approved to IEC/EN 62368-1 and UL/CSA 60950-1 standards. Its 19-inch rack system design allows for redundant configurations and supports battery charging with temperature sensors.
Mounting is via chassis, and the unit is enclosed. The LRS12-50-900G is RoHS3 compliant and meets MSL 1 requirements.
