Leading UPS manufacturer, CENTIEL, is to exhibit at Data Centre World Asia for the first time this year on booth B60. The exhibition held between 10 – 11 October 2018 at Marina Bay Sands Expo and Convention Centre in Singapore, will enable CENTIEL to demonstrate its pioneering 4th Generation Modular UPS system: CumulusPower designed to meet the critical power needs of data centres and other essential operations.
Cliff Lee, executive director of CENTIEL Asia Pacific confirms: “CENTIEL Asia Pacific is a new joint venture between my team and leading Swiss UPS manufacturer CENTIEL SA. However, we are already familiar with CENTIEL’s industry leading UPS technology as we have been a distributor since 2017. We already have more than 80 UPS systems installed in Singapore alone and are looking forward to showcasing CumulusPower at DCW Asia and introducing its many benefits to a wider marketplace.”
CumulusPower is a three-phase, modular UPS system which offers class leading “9 nines” system availability and very low total cost of ownership. Unlike traditional multi-module systems, the CumulusPower technology combines a unique Intelligent Module Technology (IMT), with a fault-tolerant parallel Distributed Active Redundant Architecture (DARA).
The excellence in system availability is achieved through fully independent and self-isolating intelligent modules – each with individual power units, intelligence (CPU and communication logic), static bypass, control, display and battery. In in the unlikely event of a module failure, the module can be quickly and safely swapped without transferring the load to raw mains.
In addition, CumulusPower has been designed to reduce the total cost of ownership through low losses: the high double conversion efﬁciency of 97.1% at the module level means it is currently the best solution available to protect data centre infrastructure as its configuration also reduces downtime risk, avoiding costly errors as well as increasing energy efficiency and it is now installed in data centres across the globe.
Cliff Lee continues: “CumulusPower is a scalable and flexible modular three-phase UPS system that combines class leading availability and efficiency that makes it ideal for use in small, medium and large datacenters. However, not every application requires a modular UPS and for these applications CENTIEL’s PremiumTower is perfect. It has the same Swiss built quality and innovative technology, with an online operating efficiency of 96.6% but comes in a lower cost, stand-alone cabinet. We will also be demonstrating PremiumTower at DCW Asia.
“We are looking forward to discussing the differences between Modular UPS technologies with delegates at the show. At the same time, we are also interested in meeting committed distributors in the Asia Pacific region whose goal is to supply world class UPS technology to protect their customers’ critical loads within their own countries.”

What do data centres require of their power delivery? The answer is easy: 100% power availability, 100% of the time. In other words, they want a system that never fails.
However, reliability is often considered the key attribute for any UPS solution. Yet, a system can be reliable over a period of time, but still fail on a particular occasion with far-reaching consequences. Therefore, availability must be the number one priority when purchasing any UPS solution.
Availability can be expressed by the following equation where MTBF equals Mean Time Before Failure and MTTR equals Mean Time To Repair:
Availability = MTBF
MTBF + MTTR
Availability is expressed as a percentage. The key number here is MTTR (if MTTR = 0 then Availability is always 100% regardless of MTBF).
In recent years, modular systems have introduced a significant step-change in the industry as, when properly configured, they are designed to maximise load availability and system efficiency simultaneously.
This is achieved because modular systems have a single frame, containing a number (N) of power modules. These run together and share the load equally between them. The advantage of this N+1 configuration is that if one module fails it becomes isolated. The remaining modules support the load and the system availability is preserved. UPS modules are paralleled vertically within a single frame, and frames can be further paralleled horizontally to provide a completely flexible system. There is no single point of failure, contributing to the highest level of availability for power protection. The load also remains protected even when any individual module is being replaced.
CENTIEL’s CumulusPower is the latest 4th generation of true modular UPS systems, incorporating Distributed Active Redundant Architecture (DARA), it provides a significant improvement over previous system designs. The critical power protection industry is, understandably, extremely riskaverse, and is particularly attentive regarding potential single points of failure. Therefore, each individual CumulusPower UPS module contains all the elements of a standalone UPS unit – rectifier, inverter, static switch, display – and critically – all control and monitoring circuitry. This eliminates the potential single point of failure associated with designs that have a separate, single static switch assembly, separate control or intelligence modules. Availability for the 4th generation Centiel system is now Nine 9s or 99.9999999%.
In addition, with all the focus on the UPS units themselves it can be forgotten that an integral element of a system is the associated batteries which provide power in the event of an electrical supply interruption or blackout. Equal consideration needs to be given to the design of the battery system, including rigorous battery autonomy calculations, selecting a quality supplier, the provision of redundant strings, individual string protection/isolation, ambient environment to name but a few.
With all the time, effort and expense of designing and installing the very best UPS system it is important that it is properly maintained to ensure availability is not compromised. Suppliers offer a variety of maintenance proposals and SLAs and diligence must be applied up front, in scrutinising and choosing the correct solution for each installations requirement. Any UPS that is not maintained properly may ultimately compromise overall system availability.
As well as availability, organizations need to consider the total cost of ownership of a UPS system and this is related to the purchase price, system efficiency (running costs) and the cost of maintenance.
I’ve touched on maintenance, so how a system is configured to maximize efficiency is another area demanding attention. The challenge is that IT requirements change quickly. So how can an infrastructure be built to meet these dramatically changing demands? Put simply, a UPS needs to operate on the best point of its efficiency curve. A system which is too small will be overloaded and a system which is too large will waste energy and be inefficient and costly to run. Scalability and flexibility are key when purchasing, to ensure the continual ‘right sizing’ of the UPS.
Modular systems offer all the advantages of high availability, scalability and flexibility to match an organization’s changing requirements. In addition, they offer the benefits of: fast replacement of modules, small footprint with high power density and, when correctly configured to ensure system “right sizing,” operating costs can be kept to a minimum.
In our ever-evolving world, future-proofing systems is one of the greatest challenges faced by system designers. The good news is that modern modular UPS systems can be quickly and easily reconfigured to adapt to changes in load requirements over time. This not only ensures the highest efficiency is maintained, but more importantly it guarantees availability of power protection whatever the future holds.

For Data Centres, power protection systems must be available every second of every day and therefore maximizing system availability must be the overriding objective of any installation. Availability is best described as the percentage of system uptime achieved in a year. To achieve maximum availability, all single points of failure within the UPS need to be removed. Over the years, many improvements have been made in relation to UPS technology and configurations to increase availability.
Availability requires duplication and redundancy which naturally introduces inefficiencies, thereby increasing energy requirements. For example: thirty years ago, the only way to achieve redundancy was to install a number of standalone UPS modules in a parallel topology. These stand-alone systems could be pretty big, for example: 60KVA UPS weighed around 600kg and was the size of a double wardrobe! In addition to the UPS modules were the associated battery systems.
The introduction of transformer-less technology in the early 1990s, by Filippo Marbach, dramatically increased efficiency, decreased size, weight and reduced costs. The true modular UPS concepts, introduced after the year 2000, resulted in even further improvements
The 4th Generation true modular UPS systems now available, provide a significant improvement over previous system designs. This is because each module contains all the power elements of a UPS – rectifier, inverter, static switch, display – and critically – all control and monitoring circuitry. This places it above other current designs that have a separate, single static switch assembly and separate control or intelligence modules as there is no single point of failure. Availability for our CumulusPower UPS which incorporates this Distributed Active Redundant Architecture (DARA) system is now ‘nine-nines’ or 99.9999999%. Hot-swap capability lowers the Mean Time to Repair (MTTR) to only around three minutes.
Scalability and flexibility are also important when installing a system to ensure the continual ‘right sizing’ of the UPS. A system which is too small will be overloaded, compromising reliability and availability. One which is too large will waste energy, be inefficient and costly to run. CumulusPower offers a flat efficiency curve across the whole load range, particularly at lower loads which are inherent in parallel redundant UPS configurations. CumulusPower offers 97% efficiency even at these low loads.
Duplication and redundancy of UPS components must also apply to the communication cables between UPS modules. The most simple communications bus is a single cable. If this breaks or becomes disconnected, the entire system could be compromised.
For this reason, the ring circuit was introduced to the majority of modern UPS systems. If the circuit breaks the signals can simply communicate the other way around the ring. The recent introduction of the Triple Mode communications bus increases system availability even further.
Like its name suggests, there are three paths of communication between UPS modules and frames made up of three separate ring circuits. Three brains communicate with three other brains – it’s the belt, braces and buttons approach.
We liken Triple Mode to the comparison of a tightrope walker. If a tightrope breaks, the consequences will be dramatic and far-reaching. In the same way, a single communications bus is far more precarious than a Triple Mode ring connection which is more like a bridge with multiple supports. Here the single points of failure are completely removed. Even if one or several bridge struts fail, the others will support the load. It does beg the question: how would you prefer to cross the chasm?
UPS technology has seen huge developments over the years. With reductions in footprint and increases in efficiency and availability, the Total Cost of Ownership is now significantly lower. The most modern UPS have become about as close to perfect as possible, keeping in mind there will always be some losses due to the very nature of switching. The incorporation of Triple Mode communications buses further mitigates the risk and moves us further towards power protection perfection.
The team at CENTIEL has been at the forefront of UPS development over the several decades. Our goal is clear: to achieve the ultimate availability of power for our client base. Our leading-edge technology, backed-up with our comprehensive maintenance contracts ensure our clients’ power has the very best protection at all times, now and in the future.

Leading Swiss Uninterruptible Power Supply manufacturer, CENTIEL SA, has introduced a simple solution to allow either top or bottom cabling connection for its three-phase, modular UPS system, CumulusPowerTM. This innovative new design now means the UPS can be connected from either high or low level, without the requirement for a separate cable entry enclosure, enabling a more flexible layout within comms rooms and data centres, maximizing the use of space and potentially reducing installation costs.
Mike Elms, sales and marketing director, CENTIEL UK explains: “Up until now, the majority of most UPS units’ final power connections are at low level within the UPS frame. This made the bending radius of larger cables a problem whether the cables were installed at floor level or, even worse, at high level and then had to be run down tray/ladder to then be worked into the bottom of the UPS frame. The solution was to install a separate: ”top cable entry” (TCE) enclosure meaning additional cost and space which can now be saved. The flexible, modular configuration of CumulusPowerTM means we are able to provide the option of having the UPS input terminals at either low or high level within the frame to accept cables from below or above depending on the site requirements.
“Our focus is to work with our clients to provide the very best UPS solutions which are most applicable for their needs. This simple but highly convenient addition of optional top or bottom cable entry, is another example of CENTIEL leading the field in UPS design for benefit of our valued customer base.”
CumulusPowerTM is CENTIEL’s leading 4th generation modular UPS system with unique Intelligent Module Technology (IMT), a fault-tolerant parallel Distributed Active Redundant Architecture (DARA), offering industry leading “9 nines” system availability and very low total cost of ownership. This excellence in system availability is achieved through the fully independent and self-isolating intelligent modules – each with individual power units, intelligence (CPU and communication logic), static bypass, control, display and battery. The solution has been designed to reduce the total cost of ownership through low losses: the high double conversion efﬁciency of 97.1% at the module level means it is currently the best solution available to protect data centre infrastructure as its configuration also reduces downtime risk, avoiding costly errors as well as increasing energy efficiency.
