Master Switch Highlights STS Installing a 4(:;,9 :>0;*/ static transfer switch provides additional resilience and protection from the disruption that can be caused by the failure of a single power source The result is the absolute protection of industrial utilities and critical information technology against power supply and load faults. Operating principle 4(:;,9 :>0;*/ guarantees a source of redundant power, allowing the load to be switched between to alternative and independent power sources. Switching can be automatic (when a supply source falls outside of acceptable tolerances) or manually done by an operator from the front panel or remotely.
