16. REMOTE BATTERY TEST -savings

Cost saving based on:
• working hours
• traveling cost reduction
• cars investment
• energy consumption
Cost saving example (working hours only)
2 persons, 8 hours for battery string
Tehnicians working and traveling hours total =20h
1hour cost =20$
1 battery string = 20h x 20$ or 400$ (labour cost only)
2000 sites x 2 battery strings =4.000x400 or 1,6 mil$
cars, fuel, equipment, energy consumption are extra cost

18. Energy & Telecommunications

Energy & Telecommunications
Consumer demand pushing growth of broadband and wireless networks
worldwide
The OPEX part of the total cost of ownership is becoming increasingly
important along with CAPEX
To meet the demands of growing telecom energy consumption and
skyrocketing energy costs, even the best power-system solutions must
continue to evolve.

19. Energy & Telecommunications

Energy & Telecommunications
Telecom systems account for 1% of worldwide electricity (and 3% in the U.S.)
15% of operational expenditures are power-related
(source: Telecommunications Industry Association)
Compare carbon footprint to the CO2 emissions of 29 million cars

20. eSure Technology Ultra efficient rectifier: Approaching 97%

Best-in-class sustained efficiency throughout a wide range of operating
conditions
Efficiencies approaching 97% starting at 30% load through to 70% load

20

21. Energy Savings Case study: eSure vs standard efficiency

Scenario:
At list price, a customer chooses to buy 1000 x 3200W eSure rectifiers vs
standard efficiency (SE) rectifiers
At 60% load, the efficiency of the eSure is 96.7% compared to 92% for SE
rectifiers
Assumptions:
Energy cost is $0.1 per KWh
Rectifiers run at 60% load
Air Condition unit has EER rating of 10 and runs at 8 hours per day
0.60kg CO2 emission per KWh consumed
Challenge:
What is the energy cost of ownership over a 10 year useful life of an eSure
rectifier vs. a standard efficiency rectifier?

Annual failure rate is the inverse of the MTBF, or 1/50= 2% per year
Assumptions:
One site visit will occur with every 2 rectifier failures
Each site visit costs $240 ($80/hour, 1.5 hour round trip, 1.5 hour onsite repair
and verification)
Full list price of replacement rectifier is incurred for each failure
Standard one year warranty on rectifiers
