An STS Cabinet (Static Transfer Switch) uses solid-state switching to transfer a load between two independent AC sources within milliseconds, fast enough that sensitive equipment sees no interruption. In data centers STS cabinets provide dual-source resilience to single-corded equipment or PDUs, seamlessly switching to the alternate feed if one source fails, enhancing power availability.
