Power supply subrack system for industrial and railway systems

Bel Power Solutions has released its new LRSA Power Supply Subrack System developed and utilised for operation in railway control centres. The system supplies redundant voltages and power for rugged railway and subway applications, solidifying its reliability and efficiency in harsh environments.

Compliant with international railway standards EN 50155, EN 50121-4, and AREMA, this series equips up to six of its 250W rugged Melcher AC/DC cassettes into one single 19” rack system, providing for a redundant input and energy output configuration. This is an enhancement from previous AC/DC Subrack System racks, which supported room for just four converters. The new rack system offers single or dual output voltages from 12 to 60VCD with up to 1500W output power and a wide input voltage range from 90 to 264VAC and 50 to 60Hz. Its wide-power range and fanless convection cooling design provide high reliability and maintenance-free operations spanning decades.

“Modern railway systems demand reliable, high-performance power systems to uphold stringent safety and security requirements both onboard and at station,” said Daniel Bernstein, president and CEO of Bel Fuse. “With this new system, railway system operators can decrease outages and operate safely and seamlessly in harsh conditions for years to come.”

The series provides high isolation of all output circuits, excellent surge and transient protection, inrush current limitation, and output voltage monitor with change-over relay contacts to provide reliable and redundant power to railway signalling and traffic control systems.
