To produce, store, transfer and restore 4 MB of datawe „burn“ the energy equivalent of 1 Kilo of coal

The actual power grid was built to supply the 3 main inventions of the last Century:

the light bulbthe electric motorthe refrigerator

Utilities provide a reliability of 99,9% = 8 hours out of tolerance/year

„good enough“ for this type of application

Energy is the Key

Static Transfer Switches

STS Static Transfer Switch

• Electronic switch that ensures uninterruptible switching between a preferred source and an alternate source. (primary or secondary)

• 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

2 Conversion Processes:

+ optimal protection for mission critical applications- increased energy losses

SS

Balance:

For less critical loads run UPS on bypass continuously

In case mains is out of limits transfer the load to inverterSuper ECO Mode: not only is the load supplied on

bypass, but the inverter is also switched off, increasing energy savings
