More Electric:
Our world is becoming More Electric. Almost everything we interact with today is either already electric or becoming electric. Think about it. From the time you start your day in the morning to the time you finish your day – your home, your car, your work, your devices, your entertainment – almost everything is electric. Imagine the energy needed to power this. Electricity consumption will increase by 80% in next 25 years
More Connected: Our lives are also becoming more connected. The Internet has already transformed the way we live, work and play. Now the Connected Things is going to take this to a brand new level. 50 billion things connected in the next 5 years.
More Distributed: With such a widespread electrification and connectivity, energy models need rethinking as well. Which is why the generation of power needs to be closer to users. Distributed Energy is rapidly evolving globally. This is positive energy – renewable. In 2014 , Renewables overtook fossil fuels in investment value, with $295bn invested in renewables compared to $289bn invested in fossil fuels. And it is getting cheaper to do this.
More Efficient: When our world is more electric, more connected and more distributed, new opportunities emerge and allows us to tap into even more efficiency – in industrial processes, in the energy value chain, in buildings, in transportation, in the global supply chain and even in the comfort and peace-of-mind of our homes.

Galaxy VX - Smart Power Test “SPoT mode”
The Smart Power Test in normal operation is conducted by circulating power from the inverter
back through the static bypass switch and into the power factor correction module. By
circulating the power, each of the UPS converters is energized and loaded in the same way as
though a UPS was feeding a load bank. The test shall be configurable for 100% rated power
continuously or 110% of rated power for 10 minutes. During Smart Power Test, the UPS shall
draw only enough power from utility to make up for system losses during the test procedure.
No need for loadbank

More Electric:
Our world is becoming More Electric. Almost everything we interact with today is either already electric or becoming electric. Think about it. From the time you start your day in the morning to the time you finish your day – your home, your car, your work, your devices, your entertainment – almost everything is electric. Imagine the energy needed to power this. Electricity consumption will increase by 80% in next 25 years
More Connected: Our lives are also becoming more connected. The Internet has already transformed the way we live, work and play. Now the Connected Things is going to take this to a brand new level. 50 billion things connected in the next 5 years.
More Distributed: With such a widespread electrification and connectivity, energy models need rethinking as well. Which is why the generation of power needs to be closer to users. Distributed Energy is rapidly evolving globally. This is positive energy – renewable. In 2014 , Renewables overtook fossil fuels in investment value, with $295bn invested in renewables compared to $289bn invested in fossil fuels. And it is getting cheaper to do this.
More Efficient: When our world is more electric, more connected and more distributed, new opportunities emerge and allows us to tap into even more efficiency – in industrial processes, in the energy value chain, in buildings, in transportation, in the global supply chain and even in the comfort and peace-of-mind of our homes.
Additional Data Points:
MORE ELECTRIC:
The rising demand for electricity driven by urbanisation, digitisation and sustainability – in particular buildings, industry, intelligent devices and even transportation -- demands proven energy management approaches.
Electricity consumption will DOUBLE within the next 20Y (urbanization). This is absolutely massive, esp. considering the yield of electricity production is around 30-40% only (3 units of primary energy to produce 1 unit of electricity). Most of the energy challenge lies into the growth of electricity production (& consumption).
MORE DISTRIBUTED:
In many parts of the world, energy generation is getting increasingly distributed. This is driven by new capabilities to provide local energy to facilities, particularly around positive or renewable energy and micro grids.
Here are two cool reasons behind this trend:
Energy storage has seen drastic improvements in its economics over the past 5 years
Li-Ion Battery cost $/Kwhr dropping from 1000 in 2010 to around 200 in 2014
Falling prices of renewable energy
Cost of Solar modules divided by 5 in last 5 years, to divide again by 2 in coming 20 years. This is now competitive with electricity prices and tariff.
Only about 0.08% of the planet needs to be equipped with solar panels to cover world energy needs (125,000km²)
Solar will reach (& already does) competitiveness with retail (& some day wholesale) prices of electricity. > Considerable modification of the traditional electricity distribution paradigm (solar + battery cheaper than retail electricity). Go for distribution of energy (small units) rather than high capex/opex power plants.
Energy of the sun everyday = 3,500 times what humanity will consume in 2050…
MORE CONNECTED:
The Internet of Things will connect 50 billion more devices in the next 5 years. Also, think of all the sensors and embedded electronics in machines on shopfloors and plants all over the world. This will add new operational intelligence from data uncovered. This, in turn, will drive vast efficiency opportunities. Connectivity, ladies and gentlemen, is pervasive – all industries, all levels of enterprise and society.
Data centers alone = 1-2% of total world electricity consumption, but the entire ICT sector = 10%.
Consumption doubled btw 2000/2005, and grew at +56% btw 2005-2010.
Digitization is also changing lives : Faster, simpler, more collaborative – More efficient
MORE EFFICINECY OPPORTUNITIES:
Our more electric world; the more distributed energy world; and the more connected world… they come together to create a more efficient world for us.
However, two-thirds of the energy efficiency potential remains untapped1. There is massive energy efficiency opportunities in Industry, Infrastructure, Buildings and Datacenters. There is also significant energy wastage due to inefficient processes in industries such as refineries, steel, and cement, to name a few.
One way to reduce this wastage is to embrace new technologies which can drive more efficient processes. Typically, the adoption of new technologies can result about 30% savings in energy consumption.
Energy is wasted by inefficient transformation industries (refineries for instance). Around 760MTOE per Y in 2013 (out of 11BTOE consumed)
Energy is wasted by inefficient power & heat transformation. Around 3,2BTOE per Y in 2013 (out of 11BTOE consumed) ! Reducing electricity consumption thus has a direct massive impact on primary resources consumption (which is why primary resource prices might remain durably low if large consumers such as Europe, NAM, China go forward with carbon reduction programs). This is just #1 topic.
Energy is inefficiently used in all segments (ref. to the slide), and massive opportunities exist.
Main paradigm: deploy what’s best (usually new tech easily consumes 30-50% less than old one).
Few e.g..
Steel industry (electrical arc furnace 5GJ/t vs traditional furnace 14GJ/t).
Cement plants (new tech 25% reduction at 3GJ/t).
Aluminium plants (13% saving only with new process & equipment)
Electric motors = 46% of total electricity consumption (64% in the industry). 21% could be saved (IEA) using EE techniques.
Buildings = 30-60% saving depending on granularity (space / time) of the “Active controls” installed. Passive isolation brings 10-15%.
Transport – Light duty = considerable progress over last decades. Up to 30% saving on fuel. And even more now with hybrid & full electric technologies. 80% of light duty transportation = small distances (within cities). Smart mobility can also take us there.
Transport – Air industry. New Boeing 787 1,3MJ/seat/km vs Boeing 767 1,9MJ/seat/km >> considerable savings
Transport – Marine. Shore connection
Main issue: willingness to change, inertia of deployment of these new tech
Lifetime of industrial plant ~ 50Y (or a power plant by the way)
Buildings: by 2050, 75% of existing buildings will still be standing
Transportation: sales of new vehicles = 7% of worldwide fleet every year + fleet is increasing (700M cars today vs 3B in 2050). >> very low rate of replacement

L'utilisation est alimentée directement au travers d'un filtre lorsque l'alimentation normale est présente et de qualité suffisante. Lors d'une défaillance de cette alimentation, l'utilisation est alimentée par l'onduleur à partir de sa batterie . Ces alimentations sont réservées aux récepteurs de faible puissance de type bureautique ou micro informatique avec une alimentation normale peu perturbée. Le temps de transfert de l'alimentation normale vers l'onduleur est de quelques millisecondes à une dizaine de millisecondes habituellement ( temps de basculement d'un relais ) .
L'utilisation est alimentée directement au travers d'un dispositif de couplage / découplage lorsque l'alimentation normale est de qualité suffisante. L'onduleur est alors en parallèle avec l'utilisation et prélève l'énergie nécessaire à la charge de la batterie. Un dispositif de filtrage peut être intercalé entre l'alimentation normale et l'onduleur afin d'améliorer le taux de distorsion de la tension et également apporter une régulation de la tension de sortie. Dans ce dernier cas le courant réactif prélevé a l'alimentation normale peut être élevé puisque c'est généralement une inductance qui supporte la différence de tension entre les deux sources.
Lors de la disparition de l'alimentation normale, le dispositif de découplage permet à l'onduleur d'alimenter directement l'utilisation. Ce dispositif de découplage doit évidemment être rapide pour éviter de perturber l'utilisation pendant le transfert des alimentations.
Bien que certaines alimentations puissent assurer une régulation de l'amplitude, la régulation de fréquence n'est pas possible et cette particularité limite leur utilisation à des alimentations normales ne présentant pas de perturbation de fréquence. Elles sont donc à éviter dans le cas où un groupe moteur thermique-générateur peut se substituer au réseau lorsque celui-ci disparaît, en raison des fluctuations de fréquence de tels dispositifs surtout pour les puissances faibles.
L'utilisation est alimentée à travers la double conversion du redresseur et de l'onduleur, à partir de l'alimentation normale , lorsque celle-ci est dans les tolérances de tension et de fréquence admissibles par le redresseur . Lorsque l'alimentation normale sort de ces tolérances l'utilisation continue d'être alimentée par l'onduleur à partir de la batterie. L'utilisation est donc en permanence alimentée par l'onduleur qui délivre une tension dont la stabilité en amplitude et en fréquence peut être très élevée. De plus le nombre de phases ainsi que les fréquences en entrée et en sortie peuvent être différents. Le redresseur et la batterie délivrent une énergie hautement disponible que l'onduleur transforme en énergie de haute qualité.
Certaines ASI comportent en plus de la chaîne redresseur / batterie / onduleur une voie by-pass, permettant généralement à travers un contacteur statique, d'alimenter directement l'utilisation en cas de forte surcharge ou d'arrêt de la chaîne précédente.
Cette voie by-pass peut être de plus raccordée à une source appelée alimentation 2, différente de l'alimentation normale afin d'augmenter la disponibilité.
Ces alimentations sont donc utilisées pour toutes les charges nécessitant un niveau de qualité élevé telles que les salles informatiques, les applications médicales ou les équipements de contrôle de procédés industriels. Elles s'imposent pour la plupart des applications lorsque l'alimentation normale est très perturbée comme dans les réseaux industriels ou ruraux.

..Power from the grid goes to the PFC… which converts the AC to DC store energy can be stored on the batteries. The Inverter the creates a new perfect sin wave to the load
Galaxy VX also supports ECO mode..... Which is a operation mode.. which only offer high efficiency.. and very low reliability…not recommended to use
Finally we have ECOnversion…. which is a combination of ECO mode… and Double Conversion…This is something NEW… we will also have a closer look at this doing the following slides -NEXT-
------ADD TO SLIDE AT SOME TIME------
Double conversion.. for tough environment
ECO mode.. for none critical applications
ECOnversion.. For the clever customer…
So before I will introduce this new innovative way solution… we need to understand the basic functionality of how a UPS works….

I would like present a new innovative UPS operation mode…. called ECOnversion…
Read line by line….
(Novel : Ny)
The benefit of ECOnversion…. is off cause the capability to safely protect the critical load.. and to remove any harmonics created by the load …and to correct the power factor.. caused by the load.. when needed….
Another major benefit of ECOnversion.. is that.. “all this” is achieved while using.. a minimum of energy… consumed by the UPS…UPS losses..
This results in “major” energy saving in the electricity consumption by the UPS… living more power to the load.. and big savings on the electricity bill for the customer..
..Lets have a closer look at the savings… we can achieve by using ECOnversion

SPoT mode… or Smart Power Test is a “On-side function test” of all critical components of the UPS.. like Power modules, SSW, Battery Charger and even the battery….
All performed with little preparation… or the requirement to rent a load bank…pulling cables to loadbank… etz.
“Read line by line” The Smart Power Test.. in normal operation is conducted by…..
3 types of SPoT mode test are available
3 types of SPoT mode test are available
SPoT mode is full functional test of the UPS… and is performed by the FSE before the critical load is connected to the UPS
The Li-ion battery solution consist of a ”LIB Rack”
Multible ”battery modules” (30,4V) are inserted in the ”Rack”
Each ”battery Module” includes 8 LIB cell’s (each 3,8V)
