Energy is the Key
The actual power grid was built to supply the 3 main
inventions of the last Century:
the light bulb
the electric motor
the refrigerator
Utilities provide a reliability of 99,9%
= 8 hours out of tolerance/year
„good enough“ for this type of application
To produce, store, transfer and restore
we „burn“ the energy equivalent of
4 MB of data
1 Kilo of coal

• Automatic operation – in case the
preferred source is out of limits (fails) the
load is automatically transferred to the
healthy alternate source.
• This transfer is seamless in case both
sources are synchronized

DC
AC
VFI concept
2 Conversion Processes:
Balance:
+ optimal protection for
mission critical applications
- increased energy losses
For less critical loads run UPS on
bypass continuously
In case mains is out of limits
transfer the load to inverter
Super ECO Mode: not only is the load supplied on bypass, but the
inverter is also switched off, increasing energy savings

Super ECO mode
• Efficiency : 98%
• to Inverter in case Bypass is out of limits
• Fast error detection
• Extremely short transfer times (<2 ms)
• User definable scheduling
• Available for 10 – 500 kVA

Intelligent Energy Management
UPS: Cost of Ownership
• Purchasing Cost & Installation Cost
• Direct Operating Cost
Efficiency = Energy Losses = Heat
• Indirect Operating Cost
Heat = air conditioning / Ventilation
• Maintenance Cost
