CumulusPower™ X1

Take single-phase protection to the next level

CUMULUSPOWER X1

CumulusPower X1, Centiel’s latest innovation, is a single-phase modular UPS solution. This cutting-edge technology brings the benefits of UPS distributed parallel architecture to single-phase critical loads. It provides the same high quality, high uptime availability power protection that has previously only been available from three-phase UPS systems.

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.

Benefits and features

When it comes to availability, it’s what’s inside that counts.

Centiel’s three-phase modular technology, referred to as Distributed Active Redundant Architecture (DARA), ensures 9-nines uptime availability with no single point of failure. With DARA, each UPS module is independent, redundant, and interconnected. Each module is a complete UPS system in its own right, with its own computing power, three independent power converters, a static bypass, and all the hardware devices needed to safely isolate a fault without impacting the load. This maximizes the mean time between failures (MTBF) and safeguards the power of your critical applications.

DARA’s Distributed Decision Making technology, referred to as DDM™, elevates redundancy by enabling collaborative decision-making among all modules. This ensures a continuous power supply to your load, even during crucial decision-making moments. With DDM, the UPS can make distributed decisions, eliminating the single point of failure typically associated with master-slave technology. As a result, downtime is minimized, and critical loads remain protected.

DARA’s technology on the frame level has been designed to accommodate non-intrusive maintenance and to minimize mean time to repair (MTTR), ensuring that any downtime is kept to an absolute minimum. For example, in the event of a power failure, frontal access to components avoids the need for removing modules, thereby reducing the risk of human error.

Benefits and features

Centiel UPSs are equipped with MEM (Maximum Efficiency Management), which ensures maximum efficiency even at underload. When the UPS is operating well below its capacity, energy efficiency can be compromised.
MEM solves this problem by intelligently adapting the number of modules to the load demand, thus optimizing resource utilization. It calculates the minimum modules required to support the load while maintaining redundancy for reliability.
Excess modules go into “active sleep” mode, significantly reducing energy consumption and maintaining system integrity. In the event of a load increase, these modules are quickly reactivated to meet the new demand. MEM’s intelligent and adaptive approach maximizes efficiency and proves to be a valuable asset in modern power management systems.

Active
The UPS module is actively operating in double conversion mode and contributing to the load alongside other active modules. The individual module’s load is proportionally distributed, with each module carrying an equal share of the full load divided by the total number of active modules.

Standby
The UPS module remains in standby mode, poised to swiftly switch to active double conversion mode if required. Its response time for the transition to active mode is measured in milliseconds, ensuring quick and seamless power delivery when needed.

Benefits and features

Leveraging peak-shaving for advanced energy management
Centiel UPSs offer a valuable peak-shaving feature that enables businesses to efficiently manage power consumption and minimize costs. By using the StratusPower peak shaving feature, businesses can strategically reduce energy consumption during peak load periods when electricity prices are typically at their highest. This results in significant cost savings while ensuring a streamlined and cost-effective power management strategy. Centiel UPSs enable businesses to proactively optimize their power consumption, making them a smart choice for sustainable and economical energy solutions.



At times of peak consumption, grid operators can demand a higher price for their power. Some of the energy stored locally in the UPS can be used at these times, reducing the amount taken from the grid. (However, UPS power reserves will never be allowed to drop below what is required to supply the critical loads.) UPS batteries can then be recharged using off-peak power.

Exploiting local energy storage in this way not only cuts upfront energy costs for the user but also reduces the excess generation capacity the power supplier has to have on hand. Local UPS energy storage also supports the ongoing move away from centralized power suppliers to distributed, renewable generation and storage.

The versatile Universal Rack UPS solution

CumulusPower is also available as a universal rack UPS and offers a blend of technical and commercial advantages tailored to meet diverse power protection requirements. This modular, three-phase UPS seamlessly integrates into any 19” cabinet, regardless of the rack’s manufacturer. With its multi-purpose design, CumulusPower simplifies the engineering and deployment of custom power protection solutions. System integrators can leverage their expertise and implement unique solutions to suit specific design needs. The UPS can be seamlessly integrated into weather-resistant enclosures, making it ideal for applications in harsh environments. The universal rack solution ensures efficient heat management, as warm air is discharged to the back of the cabinet, allowing for optimal cooling without affecting the entire enclosure. For system integrators, the universal rack solution allows efficient customization with standard products, and the opportunity to add significant local value to their power protection solutions.
