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

Static Transfer Switches
• Redundant power supplies
• Redundant cooling
• Over voltage protection
• Front access for service
• Manual bypass
• Alarm contact interface
• User friendly control panel
• Neutral dimensioned for 200%
• Unique conductivity detection

DC
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
