Technology

· 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 transfer 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.
