The Emerson UF-LTS16-1P is a single-phase automatic load transfer switch (static ATS) designed for use in critical power systems with redundant AC power inputs. It monitors two AC sources and automatically transfers the load from the preferred source to the alternate source when the primary power fails or goes out of specified limits, ensuring uninterrupted power to sensitive equipment. It is commonly used with UPS systems, PDUs, telecom and data center infrastructure.
