The Company

CENTIEL is a Swiss-based technology innovation company with a highly experienced team of designers, who have developed the first 3 phase-modular fault-tolerant UPS-system. With our passion and commitment for innovative design, product quality, and customer care, we are keeping pace with the increasing availability challenges in data centers and other mission-critical applications. Our competitive advantage relies on an open minded, direct managerial style, as well as a lean organizational structure, and quick decision making. We are able to rapidly transform new ideas into the most advanced products and solutions,by buildings on a strong mutual

respect and feeling of solidarity between our workforce and management. We place great value on the professional development of our workforce, supporting in-house and external training, as well as on-the-job training, which is a critical instrument of our personnel development program.

“The company’s resources and expertise are focused on improving the performance of our product solutions and services, to exceed our customer’s expectations.” Filippo Marbach, CEO.


The Internet has transformed the landscape of business. Big data, Industry 4.0, and the Internet of Things require a global and always-on network. As a result, traditional high-availability technology is no longer good enough. Datacenters and systems now span the globe and applications must be accessible at all times.

Meeting these higher-availability demands requires a new power protection strategy that accounts for the

increasing complexity of enterprise application infrastructures.Whereas the goal of a traditional high-availability (HA)architecture is to mitigate application downtime or outages due to failures caused by application errors or any infrastructure failure, the new goal is to eliminate any risk of downtime. The answer is CumulusPower the innovative fault-tolerant modular UPS-solution that takes availability to a new level.

The Technology

Thanks to our extensive failure analysis research and insights gathered from 25 years of field experience working with a large number of data centers and other critical environments, our power protection solutions have reached the highest levels of availability to reduce downtime risk, avoid costly errors, and increase energy efficiency. To respond to highest availability requirements i.e. to eliminate risks that may cause computer downtime of business-critical applications, CENTIEL has developed a new series of modular fault-tolerant 3phase UPS-systems called Cumuluspower (CP).

Unlike traditional centralized parallel multi-module systems, the advanced Cumuluspower technology combines a unique Intelligent Module Technology (IMT), with a fault-tolerant parallel architecture, called Distributed Active-Redundant Architecture (DARA), thereby fulfilling the highest availability and reliability requirements.

Distributed Active-Redundant Architecture (DARA)

The Distributed Active-Redundant Architecture of the multi-module UPS-system Cumuluspower was designed to respond to the highest availability requirements. This is achieved with the implementation of the “democratic” majority load trans fer decision-making in an event of a critical failure, and a correct management of the load sharing to avoid crosscurrents between the modules. The communication between the logic circuits of the modules is accomplished by means of a redundant communication BUS.

In an event of a critical failure, every module will make a decision, by means of its logic circuit, whether the load should remain on the inverter or be transferred to the bypass. The load transfer will be conducted depending on the decision made by the majority of the modules. In order to avoid crosscurrents between the modules, a master-slave load sharing technique is adopted. The first module is designated to be the master, which provides the load value to be shared by the rest of the modules (slaves). If the master experiences a failure, the next module will automatically become the leading master.

Intelligent Module Technology (IMT)

Thanks to our long experience in module-design, the Cumuluspower modules are equipped with all hardware (power circuits) and all software (intelligence and monitoring) functions, which make them fully independent and capable of safely isolating themselves from the multi-module system whenever an internal fault occurs. The rest of the multi-module system will continue to provide protected power to the critical load without interruptions. The integration of all hardware and software in each module allowed us to eliminate all the risky single points of failure that would compromise the entire system and the power to the critical data center.



CumulusPower is comprised of modules with power of 10, 20 and 50 kW, which can be accommodated in single racks with total power ranging from 20KW to 250kW. In addition, the largest power Rack CP250kW can be extended to 1.5 MW by horizontally paralleling up to 6 Racks.

The CumulusPower range is designed to protect small and mid sized Datacenters as well as other mission critical applications with a maximum power of up to 1.5 MW.

• Module IM20 (20kW)

• Module IM10 (10kW)

• Module IM50 (50kW)

These modules can be accommodated within different UPS-Racks:
Rack CP40-IB, CP80-IB, CP120-EB, CP200-EB, CP250-EB
Module IM10,IM20 IM50

Can accommodate up to 10 Modules IMT20, to build a parallel redundant configuration 9+1, with a maximum power of 200kW per rack

Can accommodate up to 5 x 50kW modules (vertical scaling) to build a redundant configuration 4+1 with maximum power of 250kW per rack. In addition, we can parallel up to 6 x Racks CP250-EB (horizontal scaling) to reach a total power of 1.5 MW, which covers a wide range of power protection applications.
