Centiel’s CumulusPower RW is a state-of-the-art, modular, redundant, EN 50121 certified UPS system. It is designed to ensure the safe and continuous flow of rail traffic. This advanced UPS solution maximizes the utilization of rail networks while reducing the cost of new infrastructure and lines by optimizing investment in control and signaling systems.
Operating 24 hours a day, 365 days a year, rail networks are the lifeline of transport. Ensuring that high-speed rail traffic can move seamlessly in multiple directions without interruption is critical to the profitability of a rail system. CumulusPower RW provides the highest level of availability to ensure efficient, on-time, safe, and reliable service.

When it comes to protecting the power supply to the railway network, Centiel’s CumulusPower UPS systems offer unique advantages. With redundancy from two sources – the public power grid and a private catenary rail power source – you can have confidence in the reliability of your rail service. The UPS can operate from a 16.7Hz or 50Hz frequency source, providing unparalleled flexibility. If one network fails, the UPS will supply power to the critical load from the other network, ensuring continuous operation. In addition, the UPS battery pack serves as a reliable energy storage option. This ensures zero downtime for critical control systems such as ETCS. By eliminating the need for backup diesel generators, it reduces greenhouse gas emissions and noise.
An outstanding feature of CumulusPower RW is the interchangeability of modules, which revolutionizes spare parts management and service. Defective UPS modules can be safely replaced online in minutes without risking the critical load. The result is minimal downtime, reduced MTTR (mean time to repair), and simplified system upgrades, all while reducing the inventory of specialized spare parts.
Centiel’s advanced UPS for railway applications is compatible with a wide range of battery types including Salt, Lithium, NiCad, VRLA, and more, ensuring optimal power backup solutions tailored to your unique needs. CumulusPower RW offers unparalleled versatility and is a reliable solution for the railway industry, ensuring seamless rail traffic, improved serviceability, and maximized uptime.
