The Bel Power Solutions LRSA32-28-900 is a high-efficiency AC-DC subrack system designed for demanding railway and industrial applications. It delivers 896W of continuous power at 28VDC with a maximum output current of 32A. The converter operates over a wide input voltage range of 90-264 VAC, making it suitable for global use.
With a minimum efficiency of 92% and a power factor greater than 0.93, the unit minimizes energy losses and meets harmonic current limits per IEC/EN 61000-3-2. The converter is compliant with safety standards UL/CSA 62368-1 and IEC/EN 62368-1, as well as railway standards EN 50155, EN 50121-4, and AREMA, ensuring reliable operation in harsh environments.
The LRSA32-28-900 is housed in a rack-mountable package measuring 435.8mm x 263.0mm x 132.6mm (17.16 x 10.35 x 5.22 inches). It features adjustable output, hot-swappable capability, active current sharing, output voltage monitoring with change-over relay contacts, inrush current limitation, and remote on/off inhibit function. These features make it ideal for redundant power systems in railway, industrial, and telecommunications applications.
