Power supplies used in railway applications must meet stringent performance and reliability standards due to the demanding environment. Key factors include ruggedness, the ability to withstand extreme temperatures, shock, and vibration, as well as compliance with industry standards like EN 50155 for electronic equipment on rolling stock. High efficiency and reliability are critical, as any power failure can disrupt operations. Power supplies must also feature robust surge protection, electromagnetic interference (EMI) filtering, and galvanic isolation to handle the electrical noise and transient voltages present in railway systems. Additionally, compact designs and high-power density are essential to save space in confined trackside or onboard installations. These characteristics ensure continuous, stable power delivery for critical systems like signalling, communication, and control in railway applications.
In addition to traditional power supplies, Powerbox offers a range of advanced solutions, including turnkey outdoor power cabinets equipped with modular rectifiers, solar MPPT modules, inverter modules, and lithium-ion batteries. These systems are designed to support solar hybrid and stand-alone power solutions for remote telecommunications infrastructure, specifically for signalling and radio communications applications.
Powerbox also can provide a suite of precision DC motors and related electro-mechanical accessories for use within onboard applications such as automatic train doors, accessibility and HVAC applications.
Powerbox provides servicing and routine overhaul services for many of the products provided for onboard railway applications, including our PBSP-74O and PBSP-74I Series Inverters. Regular and routine servicing intervals, and replacement of consumable parts help to maximise uptime and prevent unexpected downtime due to maintenance issues. If you would like to discuss routine maintenance requirements, get in touch with our Service Team today!
Yes, many of the standard Powerbox Design products you find in our range today came from these requirements. Contact us today to discuss your unique project requirements.
