OUR
STATIC TRANSFER
KEYS

Continuous transfers without interruptions via UPS or inverter systems, to or from the grid. It is an Electronic Transfer Switch Microprocessed with semiconductors (Thyristors), which selects, between a Main Source and an Alternative Source, which will feed the load (consumer).

It is used in: 1+0 System: An Inverter as the Main Source and AC Grid (Commercial) as the Alternative Source.

1+1 System: An Inverter as the Main Source and Another Inverter as the alternative source.

The Static Switch maintains the output voltage of the Inverter, Main Source, synchronized with the voltage of the alternative source (Commercial Grid) or Inverter. In case of a lack or eventual anomaly in the Main Source, the transfer to the alternative source is automatically executed. Through an internal selector switch, the priority of the sources feeding the consumers can be defined as main or alternative.
