ARCHITECTURE

Thanks to our extensive failure analysis research and insights gathered from 25
years of field experience working with a large number of data centres 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 downtime of business-critical applications,
CENTIEL has 

 

DISTRIBUTED ACTIVE-REDUNDANT ARCHITECTURE (DARA)

The Distributed Active-Redundant Architecture of the CumulusPower™ product line
is designed to respond to the highest availability requirements, through the
implementation of the “democratic” majority load transfer decision-making in the
event of a critical failure, and correct management of the load sharing to avoid
crosscurrents between modules. The communication between the logic circuits of
the modules is accomplished by means of a fault-tolerant dual communication BUS.
In the event of a critical failure, every module will decide, by means of its 



developed a new series of fault-tolerant, Three-phase, true modular UPS-systems
called CumulusPower™. Unlike traditional centralised 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.

 

 

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
becomes the master which provides the load value to be shared by the rest of the
modules (slaves). If the master fails, the next module will automatically become
the leading master.

DARA MODULAR ARCHITECTURE

INTELLIGENT MODULE TECHNOLOGY (IMT)

The CumulusPower™ modules are equipped with all hardware (power circuits) and
all software (intelligence and monitoring) functions, making them fully
independent and capable of safely isolating from the multi-module system
whenever an internal fault occurs. If that should happen, the remaining modules
will continue to provide protected power to the critical load without
interruption.

 

The integration of hardware and software in each module enables the elimination
of all single points of failure which could compromise the power of the critical
application. The core technology of the CumulusPower™ product family is based in
3 Intelligent Modules sizes that can be combined to create systems from 10kVA/kW
to 3MW


AVAILABILITY




PROTECT YOUR CRITICAL APPLICATION, MINIMISE HUMAN ERROR.


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 fulfil the needs of the most critical power
applications. CumulusPower™, true modular UPS, takes downtime from seconds to
the milliseconds level. Availability is formally defined as

MTBF
MTBF+MTTR

CumulusPower™ maximizes the Mean Time Between Failure (MTBF) while minimizes the
Mean Time To Repair with a series of future.

MINIMISED MTTR

Parallel system availability increases with the reduction of the Mean Time To
Repair (MTTR). In-frame per-module bypass fuses minimise the time it takes to
re-establish a system in an event fault.

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. CumulusPower™ parallel
communication is provided with a unique triple-mode parallel bus, that consists
of three independent communication lines and three independent electronic
circuits. With triple redundancy in the communication lines and electronic
circuits the risk of disconnection or short-circuit on any of the communication
lines is mitigated eliminating the single point of failure.

FULL BYPASS REDUNDANCY

Some UPS architectures still use centralised critical components like a Single
Bypass Architecture (SBA). Centralised components in a parallel system represent
single points of failure. Unlike the centralised architectures, Centiel’s
modular UPS, CumulusPower™, is equipped with a Distributed Bypass Architecture
(DBA), that brings full redundancy even in the bypass line, avoiding any system’
single point of failure.

SAFE SMART BATTERY TEST

CumulusPower™ 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 MINIMISED HUMAN ERROR

CumulusPower™ modules can be swapped without the need to switch over the load to
bypass. Individual module parallel isolators disconnect from the system,
minimising human error and increasing Availability.




SYSTEM COSTS

FLEXIBILITY: SAME CORE TECHNOLOGY DIFFERENT SOLUTIONS

CumulusPower™ fits in 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.”

1. REDUCED UP-FRONT INVESTMENT

Compared to a standalone UPS solutions or centralised bypass architectures,
Centiel’s scalable modular UPS have a lower total up-front investment cost,
allowing you to grow your power protection capacity as your demand increases.

2. AVOID OVERSIZED DIESEL GENERATORS

In the event of a mains failure our Unity Power Factor and Smart-Battery-Booster
ensure that every switch over happens smoothly, minimising in-rush current,
avoiding generator destabilisation and eliminating the need for generator
oversizing.

3. ELIMINATE AD-ON EXTERNAL COMPONENTS

Back-feed protection in every module and maintenance bypass, bypass fuses and
battery DC breakers within the UPS frame eliminate the need for external
components connections, reducing Total Cost of Ownership.

4. SAVE ON BATTERIES

Batteries represent a substantial part of a project cost structure. With
CumulusPower™ you have the flexibility to select the number and type of battery
blocks that best suit your application. Letting you decide on a case by case
basis the best way to optimise total system cost.

5. HIGH EFFICIENCY MEANS LESS HEAT

CumulusPower™ industry-leading VFI 97% efficiency and its flat efficiency curve,
contribute to low energy losses and heat dissipation, reducing the size and cost
of cooling systems.

6. HIGH BATTERY CHARGING CURRENT CAPABILITY

The innovative modular design of CumulusPower allows a higher charge current
capability whilst protecting the batteries at all times. This allows for faster,
safer charging.




TOTAL COST OF OWNERSHIP



MAXIMUM EFFICIENCY MANAGEMENT (MEM)

Use energy only when it is needed. Cumuluspower™ incorporates a user enabled
intelligent MEM that only uses as many modules as necessary to match the load
demand. MEM constantly looks for the optimal energy efficiency point. If the
load demand decreases, MEM calculates that a reduced number of modules could
support the load whilst still maintaining redundancy. The surplus modules enter
an “active-sleep” mode to optimise the overall energy consumption. If the load
increases, and additional modules are required to support the higher load,
“active-sleep” modules are instantaneously reactivated to support the load.

OPTIMISE VALUABLE SPACE (MINIMIZED FOOTPRINT)

With only 0.29m² for 10/20 kW and 0.44m² for 30/40/60 kW, the PremiumTower ™
optimises valuable floor space, eliminates the cost of an additional battery
cabinet, and simplifies the installation.

PROVIDE INDUSTRY-LEADING AVAILABILITY

The higher the Availability, the shorter the downtime. Eliminating single points
of failure, adding active-redundant technology, helping to prevent human error
and reducing the time to maintain and repair allows Cumuluspower™ to deliver an
industry leading Availability of 9 nines to fulfill the needs of the most
critical power applications. Cumuluspower™ reduces downtime from seconds to the
milliseconds.

Availability is formally defined as
MTBF
MTBF+MTTR

The advanced Cumuluspower™ design maximises the Mean Time Between Failure (MTBF)
whilst minimising the Mean Time To Repair.

MINIMISED LIFE-TIME MAINTENANCE COST

Preventative maintenance is important to maximize availability. Centiel develop
products to reduce the time and costs associated with preventative maintenance
and minimise the number of components that require routine replacement. The
innovative design of CumulusPower also simplifies these replacements, reducing
the time and cost involved.

PROVIDE OUTSTANDING OVERLOAD CAPABILITY (OUTSTANDING OVERLOAD CAPABILITY)

With continuous operation at 124% overload, mission critical applications will
be safe in the event of unexpected load demands.

REDUCE YOUR ENERGY BILL

High efficiency means less heat dissipation, and therefore less energy wasted.
Cumuluspower™ reduces the energy consumption of the power protection equipment
and the associated cooling systems.


USE ENERGY ONLY WHEN
IT IS NEEDED WITH CUMULUSPOWER™
ACTIVE-SLEEP MODE.




SERVICEABILITY




KEEPING A HEALTHY UPS SHOULD BE SAFE AND EASY: SERVICEABILITY

STATE OF THE ART SERVICE TOOLS

CumulusPower™ service tools allow technicians, to connect, download events,
verify configuration and change parameters of the UPS with a simple tap of the
screen. The mobile and tablet app provides a full toolbox to read and interpret
the health of the system.

SAFE POWER-UPGRADES: REDUCE HUMAN ERROR

Power capacity upgrades and module substitution are two critical operations
where human error can compromise the system load. To eliminate this risk every
module in a CumulusPower™ frame can be fully isolated from the parallel system,
thanks to the parallel isolator. This isolator allows technicians to perform a
full module test and parameters configuration in a running system without the
need for load disconnection or for your system to switch to bypass. This feature
eliminates the possibility of connecting a faulty module to the parallel system
which could compromise the connected load.

BACK-FEED PROTECTION: INCREASED SAFETY AND REDUCED SYSTEM COST

Embedded into the module as standard is back-feed protection which increases
service personnel safety, reduces total system cost and avoids external
components.

PER-MODULE 3” GRAPHICAL USER INTERFACE

With CumulusPower™ graphical user interface it is easy to read measurements,
parameters, messages, alarm and any parameter of the UPS.
