STS-100 static transfer switch(STS) is a dual-input AC converter switch, and
the other way is disconnected, and the one AC input is used to power the load. When the power supply supply is abnormal, STS will automatically switch to the other
power supply to ensure that the load is continuously supplied by the other power supply.
