STS-100 static transfer switch(STS)
In the context of power supply, the STS dual-input AC converter switch plays a crucial role. It allows for the connection of two AC inputs, with one designated input supplying power to the load under normal conditions. Once any abnormal situations such as voltage instability or power interruption occur in this power source, STS will promptly initiate the automatic switching procedure, seamlessly transitioning to the other power source to ensure the uninterrupted power supply to the load. It is especially suitable for places with extremely high requirements for power continuity, and its design based on the principle of high-speed static contactless switching endows it with numerous unparalleled advantages.
