>> USP (Unique Selling Points)

 
           
         
fficiency
 
saves money on electrical consumption
minimizes carbon impact
         
 
World wide datacenters consume more than 40 billions kW-hr every year.
The waste of energy only for UPS's represents more than 7.2 billions kW-hr which yields to 56 thousands tons of CO2 emitted every year.
Assuming all power sources converted in TSI the yearly saving is equivalent to 6,000 VW Golf at 30,000km/yr
         
ootprint 
  gains space and costs thanks to high power density
         
 
Space management is key for highly evolutive businesses. More transistors crammed into ever-smaller spaces in ICT rooms have serious repercussions on ancillary equipments and costs.
The TSI allows to address increasing demand for datacenters capacity with no compromise on physical space.
 
         

vailability
  brings broad experience in service continuity
         
 
The cost of downtime can reach sky-high levels. Rightsizing servers, routers and special technics such as virtualization even increase the risk.
Loss of service and revenues would be the most detrimental impact on a business not protected whereas the maintenance contracts may represent a significant part of operational expenses.
         

calability
  optimizes assets by scheduling investments in time
         
 
In an ideal world the ICT manager would know the development of his business and have an accurate plan for resources acquisition. In the real world, the business growth beyond the year is rather uncertain.
The TSI is especially designed to support fast and seamless growth without power disruption. Your financial executive will love spreading out the investment according to the evolution of the revenue.

>> Reduce Energy losses by more than 60%

Global efficiency of an efficient traditional system Rectifier/Battery/Inverter is 85%

Efficiency of TSI in EPC mode 95%

 

Let’s assume a 20 kW DC/AC Inverter system loaded at 80%

Total AC input power consumption to supply the load:

 

  Traditional solution: 164.895,00 kWh per year
  TSI solution in EPC: 147.538,00 kWh per year
  Total Saving: 17.357,00 kWh per year

 


In a telecom environnement, the cooling need to be taken into consideration. Every kWh saved in cooling is
40 % less consumption of electricity.

 

Total saving including cooling: 28.928,00 kWh per year

 

Cost per kW/h 0,1 EURO
  Total saving per year 2892, 9 EURO per year

>> Carbon Impact

To produce 1 kW/h of electricity the carbon CO² impact is approximately 0,5 kg using fossile source of energy "Gaz combined”. For Coil the carbon impact is even more severe 0,9 Kg CO2 for 1 kWh/h

Total benefit using TSI in EPC mode versus DC/AC ON LINE for our 20 kW inverter is 8,7 tons of carbon dioxid CO2

Save the planet!!!!!!!

>> EPC mode of operation

The EPC “Enhance Power Conversion” mode of operation is to supply the AC output from the AC input when AC input is present.

> The Efficiency is significantly improved up to 96% compare to traditional DC/AC Inverter

> Each TSI module has a AC input filtering that filter the harmonics of the load

> The AC output is pure sine and stabilized with a wide AC input range (150Vac to 275Vac) make the TSI concept convenient for sensible application very dependent on AC voltage quality, amplitude and waveform

Top

>> No single point of failure

Traditional DC/AC modular inverter system have external static by-pass switch (STS) which introduce limitation

> The maximum capacity of the installation is limited to the size of the static switch.

> The Static switch is a ‘single point of failure’ and the MTBF of the system is limited to the MTBF of the static switch

> Obligation to operate the “manual by-pass” for replacing the static switch module

TSI concept is designed to:

> have no limits to the number of unit in parallel (max 32)

> static switch functionalities are integrated in each module

> Manual by pass is now a “Maintenance by-pass” maintenance only

>> AC mains filtering

Harmonics, Spikes, Surge, Burst, low voltage; high voltage ….all those small events that has dramatic consequence on your critical and sensitive application.

Countries where the AC commercial power grid is really poor generates a lot of problems in residential, commercial office, even critical and sensitive load can be damaged.

Conventional modular DC/AC inverter equipped with STS gives possibility to work OFF LINE:

All events described above will be directly transferred to the load

Sensitive load (ICT equipments) can be severely damaged and increase the risk of downtime

The new TSI AC power concept brings you:

> Unity power factor on AC input (It filter harmonics and therefore increase the global PF of your installation

> Line conditioner as it filter events listed above and provide perfect full sinus at AC output

> Table full sinus output not related to AC input voltage

> The AC commercial grid can vary between 150VAC and 275VAC

>> AC Distribution selectivity

What is selectivity?

Selectivity between 2 circuit breakers (upstream and downstream) is related to the necessary current to trip the downstream breaker while the upstream breaker stays in operation.

When a PDU supplies sensitive equipment it is very important -if there is a incident in one AC load (Short-circuit) to open the circuit breaker in less then 10 mS in order not to disturb other sensitive equipment.

UPS or inverter with STS will use the commercial power grid is they are not providing power but as the peak current could be very high there is a risk to trip alos the upstream breaker.

TSI brings the solution thanks to his “Boost” performance that can provide 10 x the nominal current during 10 mS. The module TSI BRAVO 48V-2500VA-EPC will give 100 AMPS for 10mS enough to trip one 10 A circuit breaker.

> TSI control the current to avoid tripping of upstream breaker

> TSI brings facilities to size the PDU and potential reduction of cost

> TSI providing 10 x In allows tripping within 10 mS

>> Evolutive Architecture

Conventional architecture requires external static switches which introduce single point of failure and does not guarantee proper AC selectivity of the upstream and downstream distribution.

TSI open new architecture where STS (Single point of failure) are not needed and where TSI concept can grant the upstream and downstream AC distribution selectivity, high level of reliability and a total flexibility.
