Transfer Systems for Data Centers
In modern Data Centers, where downtime is not an option, Static Transfer Systems (STS) are essential components of a robust power infrastructure . Designed to automatically switch the load between two independent power sources without interruption, STS units guarantee continuous operation —even in the event of a failure in one of the input sources.
