• Availability to the Next Level 99.9999999% (9 nines)                                                                                                                                     The higher the Availability, the lower the downtime. By eliminating any single point of failure, adding active-redundant technology, preventing human error and reducing the time to maintain and repair, Cumuluspower™ delivers an industry leading Availability of 9 nines to fulfill the needs of the most critical power applications. CumuluspowerTM takes downtime from seconds, to the milliseconds level. Availability is formally defined as the MTBF/(MTBF+MTTR). Cumuluspower™ maximizes the Mean Time Between Failure (MTBF) while minimizes the Mean Time To Repair with a series of futures.                                                                                                                                                                           
• Triple-mode parallel bus                                                                                                                                                                                   Multi frame connection is one of the advantages of horizontal scalability. Communication between frames and modules is critical, nevertheless for some architectures it is still a single point of failure. CumuluspowerTM parallel communication is provided with a unique triple-mode parallel bus, that consists of three independent communication lines and three independent electronic circuits. Disconnection or short-circuit on any of the lines does not represent a risk for the system thus eliminating the single point of failure.                                                                                                                                     
• Full Bypass redundancy                                                                                                                                                                                Some UPS architectures still use centralized critical components like a Single Bypass Architecture (SBA). Centralized components in a parallel system represent single points of failure. Unlike the centralized architectures, Centiel’s modular UPS, CumulusPowerTM, is equipped with a Distributed Bypass Architecture (DBA), that brings full redundancy even in the bypass line, avoiding any system’ single point of failure.
  
  
• Minimized MTTR                                                                                                                  ​                                                                           Parallel system availability increases with the reduction of the Mean Time To Repair (MTTR). In-frame per-module bypass fuses minimize the time it takes to reestablish a system in an event of output short-circuit.                                                                                                                                 
  
• Safe Smart Battery Test                                                                                                                                                                    CumulusPowerTM battery tests are programmable and safe. Smart Battery Booster architecture, allows the UPS to perform battery monitoring, tests and health status diagnosis without the need for mains disconnection.                                                                                                      
• Hot-Swappable with Minimized Human Error                                                                                                                           CumuluspowerTM modules can be swapped without the need to switch over the load to bypass. Besides that, a per-module parallel isolator fiscally isolates the module from the system minimizing human error and increasing Availability.

Flexibility: Same core technology different solutions 

CumulusPowerTM fits on a 19” (IM10/20) to provide the maximum flexibility to the final application. Centiel’s flexible solution approach can customize a frame solution to satisfy specific needs.

• Maximum Efficiency Management (MEM)                                                                                                                                                                  Use energy only when it is needed. CumulusPowerTM product line implements an intelligent MEM, that uses as many modules as necessary to match the load demand. MEM looks for the most optimized energy efficiency point, if load demand decreases and a lower number of modules can handle the load while maintaining redundancy, the superfluous modules enter into active-sleep mode to optimize overall energy consumption. Active-sleep modules are ready to instantly take any load shall it increase.                                                                                                                   
• Reduce your energy bill                                                                                                                                                                                            High efficiency means less heat dissipation, thus, less energy wasted. CumulusPowerTM lets you reduced your energy consumption on power protection and cooling system.                                                                                                                                                                                                              
• Minimized life-time maintenance cost                                                                                                                                                                    Maintenance is an important factor to increase availability. CumulusPowerTM product line was designed to reduce the number of components that need replacement while at the same time reduce the time and cost of such maintenance operations.                                                                                   
• Easy replaceable plug and play components                                                                                                                                                              Due to technology reasons, AC capacitors need a periodic replacement. This preventive maintenance is important to guaranty availability. Centiel has designed an easy to maintain mechanism that simplifies the process while reducing the total cost of the operation.                                                    
• Reduction costs on DC capacitors maintenance                                                                                                                                                        DC capacitors are normally replaced every 5 to 6 years. CumulusPowerTM’s DC bus is designed to make DC capacitors last for a minimum of 10 years without the need of replacement*. Thus minimizing the total life-time cost.* Module IM10/20

• Continuous Power Availability                                                                                                                                                                                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 CumuluspowerTM (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 CumuluspowerTM 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 CumuluspowerTM 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.
