Static Transfer Switch

Transfers without interruption of UPS or inverter systems, to network or vice versa.
It is a Microprocessed Electronic Transfer Switch that uses semiconductors (thyristors), which selects, between a main and an alternative power supply, which will power the load (consumer).

It is used in:

System 1 + 0: An inverter as the main power supply and the AC network (commercial) as an alternative power supply.
System 1 + 1: An inverter as the main power supply and another inverter as an alternative power supply.

The Static Switch maintains the output voltage of the inverter and the main power supply synchronized with the voltage of the alternative power supply (commercial network) or Inverter. In case of lack or eventual failure of the main power supply, the transfer to the alternative power supply is performed automatically. Through an internal selector switch it is possible to configure the priority of the power supplies that power the consumers, main or alternative.
