Uninterruptible Power Supply with the The highest availability

CumulusPower^TM is comprised of modules with power of 10, 20, 25, 50 and 60 kW, which can be accommodated in single racks with total power ranging from 20KW to 600kW. In addition, the power Racks can be extended to 3,6 MW by horizontally paralleling up to 60 modules. The CumulusPowerTM range is designed to protect small and mid-sized Datacenters as well as other mission critical applications with a maximum power of up to 3,6 MW.

Flexibility: Same core technology different solutions

CumulusPower^TM 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.

• 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 Cumuluspower^TM (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^TM 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^TM 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.

• Unity Power Factor
  (kVA = kW)

  PremiumTower ™ provides unity power factor which avoids the need for system over size to support today’s power factor corrected loads.

• High Efficiency
  96.6% (VFI)

  With a best in class efficiency of 96.6% in double conversion mode (VFI), PremiumTower ™ provides the lowest Total Cost of Ownership.

• High Battery
  Charging current

  With the ability to provide up to 5 times more charging current than typical standalone ups, PremiumTower ™ reduces the total system cost by eliminating the need for external battery chargers.

• Outstanding
  Overload Capability

  With a 124% continuous operation in overload condition, mission critical applications can be safe on the event of unexpected load demands.

• Ultra-Safe
  Eco mode

  With a 99.4% efficiency in Eco mode operation and an ultra fast reaction time of <1.9 ms, Ultra-Safe Eco mode enables an excellent trade-off between power quality and energy efficiency.

• Exceptional Short
  Circuit Capability

  With a Short Circuit Capability of 3 times nominal current (3 x In), PremiumTower ™ is able to clear output circuit protection in milliseconds.

Products

Centiel’s product line CumulusPowerTM is the latest
generation of fault-tolerant modular UPS solutions.
CumulusPowerTM intelligent modules can be connected in
parallel configurations to provide redundancy or to
increase the system’s total capacity. The CumulusPowerTM
comes in three module sizes IM10 (10kW) , IM20 (20kW)
and IM50 (50kW). The IM10 and IM20 modules are of the
same physical size and can be fitted in four different
Racks CP40-IB, CP-80-IB, CP120-EB and CP200EB
(IB=Internal Battery and EB=External Battery), whereas
the module IM50 can be fitted in a CP250-EB Rack.
In addition up to 6 x Racks CP250-EB can operate in
parallel configuration to build a system with a maximum
power of 1.5 MVA.
