Centiel CumulusPower - Model X1 - Single-Phase Modular UPS
CumulusPower™ X1 represents an innovative leap in single-phase modular UPS solutions by incorporating Centiel's three-phase Distributed Active Redundant Architecture (DARA). This advancement ensures enhanced availability with a remarkable '9 nines' (99.9999999%) uptime, addressing the needs of critical application sectors such as healthcare, finance, and banking. The system's robust fault-tolerant architecture eliminates single points of failure, with each module fully independent and equipped with redundant features including a static bypass and individual power converters. The 10kW or 20kW capacity, along with a 20kW N+1 redundancy option, optimizes energy management through Maximum Efficiency Management (MEM), adapting resources to load demands efficiently. Additionally, the integration capability into 19” racks or standalone cabinets with battery options curtails infrastructural changes and maximizes space efficiency, making it an optimal choice for environments like surgical operating rooms demanding high safety and cost efficiency.
With CumulusPower X1, Centiel has revolutionized the single-phase modular UPS market by integrating the functionality of its three-phase Distributed Active Redundant Architecture (DARA) into this new solution, ensuring customer convenience and the highest level of power protection.
The response to this development has been unprecedented. This is particularly true in sectors such as healthcare, finance, and banking. The single-phase modular UPS offers increased availability, with “9 nines” (99.9999999%) availability to eliminate system downtime, and outstanding online efficiency of 97.1% to minimize running costs. Safe-Hot-swap modules eliminate human error during operation. The use of high-quality, long-life components significantly reduces the total cost of ownership (TCO).
The CumulusPower X1 is available as a three-phase input, single-phase output, or single-phase input/output. Its power comes in 10kW or 20kW capacity or 20kW N+1 redundancy in a single cabinet. Various cabinet types are available, including those with integrated batteries and rack-independent enclosures, allowing seamless integration into existing 19” racks and maximizing space utilization.
This solution eliminates the need for costly changes to a site’s electrical infrastructure. It also makes high-level power protection accessible to single-phase critical loads. The single-phase modular CumulusPower X1 is a breakthrough in single-phase power protection, easily installed in 19” racks or discrete UPS cabinets.
The integration of in-rack batteries not only increases cost efficiency but also significantly reduces the floor space required, making it an ideal and space-saving solution for surgical operating rooms.
